-# Ring Benchmark Results
-
-Generated by `lib/erlang/bench_ring.sh` against `sx_server.exe` on the
-synchronous Erlang-on-SX scheduler.
-
-| N (processes) | Hops | Wall-clock | Throughput |
-|---|---|---|---|
-| 10 | 10 | 907ms | 11 hops/s |
-| 50 | 50 | 2107ms | 24 hops/s |
-| 100 | 100 | 3827ms | 26 hops/s |
-| 500 | 500 | 17004ms | 29 hops/s |
-| 1000 | 1000 | 29832ms | 34 hops/s |
-
-(Each `Nm` row spawns N processes connected in a ring and passes a
-single token N hops total — i.e. the token completes one full lap.)
-
-## Status of the 1M-process target
-
-Phase 3's stretch goal in `plans/erlang-on-sx.md` is a million-process
-ring benchmark. **That target is not met** in the current synchronous
-scheduler; extrapolating from the table above, 1M hops would take
-~30 000 s. Correctness is fine — the program runs at every measured
-size — but throughput is bound by per-hop overhead.
-
-Per-hop cost is dominated by:
-- `er-env-copy` per fun clause attempt (whole-dict copy each time)
-- `call/cc` capture + `raise`/`guard` unwind on every `receive`
-- `er-q-delete-at!` rebuilds the mailbox backing list on every match
-- `dict-set!`/`dict-has?` lookups in the global processes table
-
-To reach 1M-process throughput in this architecture would need at
-least: persistent (path-copying) envs, an inline scheduler that
-doesn't call/cc on the common path (msg-already-in-mailbox), and a
-linked-list mailbox. None of those are in scope for the Phase 3
-checkbox — captured here as the floor we're starting from.

-\ ------------------------------------------------------------------------------
-\ Version 0.15 1 August 2025 Added two tests to VALUE
-\         0.14 21 July 2022 Updated first line of BUFFER: test as recommended
-\              in issue 32
-\         0.13 28 October 2015
-\              Replace <FALSE> and <TRUE> with FALSE and TRUE to avoid
-\              dependence on Core tests
-\              Moved SAVE-INPUT and RESTORE-INPUT tests in a file to filetest.fth
-\              Use of 2VARIABLE (from optional wordset) replaced with CREATE.
-\              Minor lower to upper case conversions.
-\              Calls to COMPARE replaced by S= (in utilities.fth) to avoid use
-\              of a word from an optional word set.
-\              UNUSED tests revised as UNUSED UNUSED = may return FALSE when an
-\              implementation has the data stack sharing unused dataspace.
-\              Double number input dependency removed from the HOLDS tests.
-\              Minor case sensitivities removed in definition names.
-\         0.11 25 April 2015
-\              Added tests for PARSE-NAME HOLDS BUFFER:
-\              S\" tests added
-\              DEFER IS ACTION-OF DEFER! DEFER@ tests added
-\              Empty CASE statement test added
-\              [COMPILE] tests removed because it is obsolescent in Forth 2012
-\         0.10 1 August 2014
-\             Added tests contributed by James Bowman for:
-\                <> U> 0<> 0> NIP TUCK ROLL PICK 2>R 2R@ 2R>
-\                HEX WITHIN UNUSED AGAIN MARKER
-\             Added tests for:
-\                .R U.R ERASE PAD REFILL SOURCE-ID 
-\             Removed ABORT from NeverExecuted to enable Win32
-\             to continue after failure of RESTORE-INPUT.
-\             Removed max-intx which is no longer used.
-\         0.7 6 June 2012 Extra CASE test added
-\         0.6 1 April 2012 Tests placed in the public domain.
-\             SAVE-INPUT & RESTORE-INPUT tests, position
-\             of T{ moved so that tests work with ttester.fs
-\             CONVERT test deleted - obsolete word removed from Forth 200X
-\             IMMEDIATE VALUEs tested
-\             RECURSE with :NONAME tested
-\             PARSE and .( tested
-\             Parsing behaviour of C" added
-\         0.5 14 September 2011 Removed the double [ELSE] from the
-\             initial SAVE-INPUT & RESTORE-INPUT test
-\         0.4 30 November 2009  max-int replaced with max-intx to
-\             avoid redefinition warnings.
-\         0.3  6 March 2009 { and } replaced with T{ and }T
-\                           CONVERT test now independent of cell size
-\         0.2  20 April 2007 ANS Forth words changed to upper case
-\                            Tests qd3 to qd6 by Reinhold Straub
-\         0.1  Oct 2006 First version released
-\ -----------------------------------------------------------------------------
-\ The tests are based on John Hayes test program for the core word set
-
-\ Words tested in this file are:
-\     .( .R 0<> 0> 2>R 2R> 2R@ :NONAME <> ?DO AGAIN C" CASE COMPILE, ENDCASE
-\     ENDOF ERASE FALSE HEX MARKER NIP OF PAD PARSE PICK REFILL
-\     RESTORE-INPUT ROLL SAVE-INPUT SOURCE-ID TO TRUE TUCK U.R U> UNUSED
-\     VALUE WITHIN [COMPILE]
-
-\ Words not tested or partially tested:
-\     \ because it has been extensively used already and is, hence, unnecessary
-\     REFILL and SOURCE-ID from the user input device which are not possible
-\     when testing from a file such as this one
-\     UNUSED (partially tested) as the value returned is system dependent
-\     Obsolescent words #TIB CONVERT EXPECT QUERY SPAN TIB as they have been
-\     removed from the Forth 2012 standard
-
-\ Results from words that output to the user output device have to visually
-\ checked for correctness. These are .R U.R .(
-
-\ -----------------------------------------------------------------------------
-\ Assumptions & dependencies:
-\     - tester.fr (or ttester.fs), errorreport.fth and utilities.fth have been
-\       included prior to this file

-A "chunk" is any preprocessed segment ending at a \`}T\` (every Hayes test
-is one chunk, plus the small declaration blocks between tests).
-The runner catches raised errors at chunk boundaries so one bad chunk
-does not abort the rest. \`error\` covers chunks that raised; \`fail\`
-covers tests whose \`->\` / \`}T\` comparison mismatched.

-A "chunk" is any preprocessed segment ending at a `}T` (every Hayes test
-is one chunk, plus the small declaration blocks between tests).
-The runner catches raised errors at chunk boundaries so one bad chunk
-does not abort the rest. `error` covers chunks that raised; `fail`
-covers tests whose `->` / `}T` comparison mismatched.
-
-### Chunk cap
-
-`conformance.sh` processes the first `$MAX_CHUNKS` chunks (default
-**638**, i.e. the whole Hayes Core file). Lower the cap temporarily
-while iterating on primitives if a regression re-opens an infinite
-loop in later tests.

-## Notes
-
-- The spec interpreter is correct but slow (call/cc + dict-based ivars per send).
-- Larger Life multi-step verification, the 8-queens canonical case, and the glider-gun pattern are deferred to the JIT path.
-- Generated by `bash lib/smalltalk/conformance.sh`. Both files are committed; the runner overwrites them on each run.

-;; SUnit — minimal port written in SX-Smalltalk, run by smalltalk-load.
-;;
-;; Provides:
-;;   TestCase     — base class. Subclass it, add `testSomething` methods.
-;;   TestSuite    — a collection of TestCase instances; runs them all.
-;;   TestResult   — passes / failures / errors counts and lists.
-;;   TestFailure  — Error subclass raised by `assert:` and friends.
-;;
-;; Conventions:
-;;   - Test methods are run in a fresh instance per test.
-;;   - `setUp` is sent before each test; `tearDown` after.
-;;   - Failures are signalled by TestFailure; runner catches and records.
