Using threads and fork together seems to be a big smelly armpit in Python.
There are also problems on redhat9, where signals in a fork+exec'd
subprocess are blocked, for instance.  This seemed to be a consequence
of blocking all signals in thread_pthread.h:PyThread_start_new_thread().
Perhaps pthread_atfork() could be used to fix this problem, though I
know next to nothing about pthreads beyond the documentation I glanced
at back when I first became aware of my thread+fork problem and before
writing this message.
