My problem is that if Python is embeded, my module will still be active
after Py_FinalizeEx(). For example, if it installed an handler for the
SIGSEGV signal: a segmentation fault will call the handler which will
try to get the interpreter state, but there is no more interpreter. I
don't know if it is a problem or not, but I would prefer to cleanup my
module on Py_FinalizeEx().

I can try to ensure that Python does restore all signals installed by
faulthandler and cancel the current alarm() (used by
dump_traceback_later()). Or I can hardcode something to unload
faulthandler in Py_FinalizeEx() (or somewhere else).
