I am still bothered by the fact that,

>>> import faulthandler
>>> faulthandler.enable()
>>> import sys
>>> sys.stderr.close()
>>> sys.stderr = open('logs/error.log', 'wb')
>>> faulthandler.sigsegv()

, does the wrong thing. In this incantation, it's easy to say that it's
programmer error, but I think this still precludes it from being on by
default (where the first two statement are implicitly executed by the
interpreter). It's probably uncommon enough to close stderr from an
interactive interpreter session that it doesn't bother me (although I am
not sure the utility of that), but I would hesitate to say that is true
for using '-i'.

Otherwise, the functionality seems generally useful and it's on my list
of things to integrate into my application, and having it in the stdlib
is one less external dependency for me to manage.
