"When I tested the threads branch on Darwin/PPC, there was a stretch of
about 8 tests in one file which caused 'make test' to grind to an
absolute halt. My laptop did not freeze, but 'make test' just silently
stopped.
These poor results on this platform persist. In the threads branch,
building on Darwin/PPC with --cc=gcc --link=g++ --ld=g++ (same as I've
done since 2006), 'make test' (running TEST_JOBS=1) hangs on
t/pmc/nci.t, starting at around test 37.
When I run the individual tests, I get inconsistent results. More often
than not, the individual tests pass -- even though the overall test file
hangs. Sometimes the individual tests hang as well.

One instance of './parrot /Users/jimk/gitwork/parrot/t/pmc/nci_37.pasm'
completed successfully (above), but 'make test' has been hung at a
previous instance of that test for 18 minutes.
Note also that t/pmc/nci_42.pasm hung to the point where I had to kill
it, but then it subsequently ran correctly.
So I've now observed inconsistent or poor results in t/pmc/nci.t in the
threads branch on two different platforms.
I don't think it's ready for prime time.
Thank you very much.
