[Python-Dev] Trap SIGSEGV and SIGFPE

[BJörn Lindqvist]

One thing i think it would be useful for in the real world is for
unittesting extension modules. You cant profitably write unit tests
for segfaults because that breaks the test harness. In situations like
those, recovering would be likely (caveat emptor of course).
