I'm also concerned with this test because it does not fail in nightly

I've been experimenting with this test in an effort to find
under what conditions the SIGSEGV can be reliably reproduced.
It seems as though the likelihood of it running successfully
to completion increases as the number of threads decreases
below the number of processors. For example, with just two
threads running (on an 8 CPU box), the test hasn't failed
in nearly 40 executions. But with the number of threads in
excess of the number of processors I can pretty reliably
cause the test to fail with the error below:
/amd/devco/sebor/stdcxx-4.2.x/include/loc/_locale.h:364:
__rw::__rw_get_std_facet: Assertion '0 != __pfacets' failed.
This suggests a thread safety bug in the library...
What's even more concerning than the bug itself is that we
run all our thread safety tests with the same number of
threads as there are processors on each server. If other
hardware behaves similarly to PowerPC, we might need to
bump up this number (and discover a whole bunch more
problems...)
