[Python-Dev] Need to hook Py_FatalError

Your efforts would be better directed towards fixing the causes of the
fatal errors.

I see no need to hook Py_FatalError, but since it's open source, you
are of course free to patch your own copy if your urge is truly
irresistible. Or I guess you could run Python under supervision of gdb
and trap it that way.

But tell me, what do you want the process to do instead of
terminating? Py_FatalError is used in situations where raising an
exception is impossible or would do more harm than good.
