procedure, call it like a thunk.

* module/language/assembly/decompile-bytecode.scm (decode-load-program):
* module/language/assembly/compile-bytecode.scm (compile-bytecode): Add
case for bind-optionals/shuffle-or-br.

(scm_sym_documentation): ... this. Make it global.

[sans-extension]: New procedure.
[load-absolute]: Call (stat ABS-PATH) from here. Search a `.go' file
from %LOAD-COMPILED-PATH before searching %COMPILE-FALLBACK-PATH.
This allows it to actually use all CPU cores, instead of having the main
thread stuck on a `wait-condition-variable'.
* module/ice-9/threads.scm (par-mapper): Add a `cons' argument; update
callers accordingly. Rewrite using nested futures.
* module/ice-9/futures.scm (%futures-waiting, %within-future?,
%future-prompt): New variables.

(process-futures): Move loop body to...
(process-one-future): ... here. New procedure.
(notify-completion): New procedure.
(touch)[work, loop]: New procedures.
When %WITHIN-FUTURE? and FUTURE is started, abort; if not
%WITHIN-FUTURE, call `work' while waiting.
When FUTURE is queued, call `work' too.
* test-suite/tests/future.test ("nested futures"): New tests.
* module/ice-9/futures.scm (<future>)[completion]: New field.
[done?]: Rename to...
[state]: ... this. Change `set-future-done?!' to

an exception is thrown. Within the critical section, check to make
sure the worker pool hasn't already been created by another thread.

argument list to match the actual fields present.
(make-option-spec): Update to match the fixed %make-option-spec.
