This patch updates Python/thread_pthread.h to mask all signals for any thread created. This will keep all signals masked for any thread that isn't the initial thread. For Solaris and Linux, the two platforms I was able to test it on, it solves bug #465673 (pthreads need signal protection) and probably will solve bug #219772 (Interactive InterPreter+ Thread -> core dump at exit). I'd be great if this could get some testing on other platforms, especially HP-UX pre 11.00 and post 11.00, as I had to make some guesses for the DCE thread case. AIX is also a concern as I saw some mention of using sigthreadmask() as a pthread_sigmask() equivalent, but this patch doesn't use sigthreadmask(). I don't have access to AIX. Note that thread_pthread.h.orig in this patch is the unmodified version from the Python2.1 release.
