The languages left the nest with Parrot 1.0, and many libraries will

My main goal is to build& test them without Perl5 dependency.
See runtime/parrot/library/distutils.pir& runtime/parrot/library/TAP.
General agreement that this is a good long-term goal, and good to be
making progress on it.
My current needs are :
- a way to chmod file (see TT #1322)
- a TAR library (first creation)
- a zlib library (first compression)
All considered good ideas.
I want to experiment the parallel build& test (option --jobs=Nb core).
With the subroutine run_jobs (see above), distutils is ready for a refactoring
.sub 'run_jobs' # serial build
.param pmc jobs
L1:
unless jobs goto L2
$S0 = shift jobs
system($S0, 1 :named('verbose')) # mainly, a spawnw $S0
goto L1
L2:
.end
but I don't known which parallelism model is supplied by Parrot.
Parrot currently provides a layer over POSIX threads (or Windows threads
on Windows). They have limitations, but are adequate for this kind of
simple parallelism (each parallel task is largely independent of
another). The tricky part for you is likely to be deciding how to
declare when a build job can be run in parallel, and when one job has to
wait for another to complete.
