I agree, recovering from segfaults caused by buggy third party C
modules is a losing proposition, but for a limited number of
conditions that can be triggered from python code running on a
non-buggy interpreter (hopefully ctypes included, but that would be
hard), converting signals into exceptions may be possible.

Even a simple dialog: Python have encountered a segfault, would you
like to dump core? y/n in the interactive session will be quite
useful.
