[boost] [thread] SunPRO: test_mutex hangs when run via regression.py

From: Caleb Epstein (caleb.epstein_at_[hidden])

The Boost.Threads test program test_mutex, when built with the SunPRO
C++ compiler, always hangs when I run it on a Solaris machine under
regression.py.  The same binary finishes in short order with status 0
when run on the command line, but under regression.py it never exits. 
If I attach to it with the debugger, or with strace or truss, it
finishes successfully.

I'm unclear what could be going wrong here and expect it is either a
bug in the code produced by SunPRO or a really subtle bug in the test
program.  Perhaps someone could take a look?  I am stumped.  Here's
the output of a program I found called "thrstack" which produces a
stack trace for each thread w/o attaching to it:
