New submission from Ned Deily <n...@acm.org>:
I've recently started seeing occasional regression test error messages
on OS X from test_thread. The test reports running OK but tracebacks
are displayed. It's not reproducible at will but has shown up on both
10.5 Intel and 10.5 PPC machines with various recent top of py3k builds.
Here are two examples:

Are the tracebacks from a harmless race condition and, if so, can the
test be modified to eliminate them? Or is there some new real problem?
