I've run 'check-guile threads.test' by itself, and the check-guile.log 
shows:

So it seems to be hanging on the
(with-test-prefix "cancel-thread" ...) section.
Even the first sub-test (pass-if "cancel succeeds" ...) hangs 
indefinitely.

If I comment out that section for now, at least the tests finish, but 
with one more failure:

FAIL: threads.test: mutex-ownership: mutex with owner not retained (bug #27450)

Totals for this test run:
passes:                 40
failures:               1
unexpected passes:      0
expected failures:      0
unresolved test cases:  0
untested test cases:    0
unsupported test cases: 0
errors:                 0

I was informed on another mailing list that thread-cancellation might not 
be supported on darwin8:
http://mailman.videolan.org/pipermail/vlc-devel/2009-September/066428.html

If this is indeed the case, is there any hope for testing/supporting 
threads on powerpc-apple-darwin8?
