I've been testing out GNU guile-1.9.6 (alpha) for a few days, preparing an experimental fink package, and ran into a test failure in their test suite which seeks explanation. On OS X 10.4 (powerpc- darwin8), their tests on threads hang indefinitely in the section on thread-cancellation. The same (and all) tests pass on 10.6 (i686- darwin10). How is thread cancellation supported in darwin8 (if at all) differently than in darwin10? I'm looking for any hints on where to start debugging, if this is something that can be fixed.

I guess that Mac OS X 10.4 simply supported fewer cancellation points. IIRC, the only one it supported was pthread_testcancel. See http://lists.apple.com/archives/Darwin-kernel/2004/Jan/msg00032.html
