Review Comment:
So this one is slightly odd. It's def triggerable 100% of the time for me.
Acording to python `threading` module there is only a single thread at the
point of calling `os.fork`.
The odd thing here is that if I import `setproctitle` eagerly before fork,
then the SIGSEGV goes away, but Py 3.12 now starts complaining about "This
process (pid=96305) is multi-threaded, use of fork() may lead to deadlocks in
the child."
