After experimenting, I understand the motivation for this change here, but I also worry that it might affect other workflows we haven't considered. Could there be other use-cases where a different Exception occurred and pdb._user_requested_quit is True, but we would want that to fall through (not break)?

Good question. self._user_requested_quit will be True only when we get quit()/exit() or EOF. ISTM that it's safe to exit in both cases.

I'm pretty sure I've had to kill pdb processes in the past, when they stopped responding to quit(), so I would guess it's more likely that there are other code paths that would benefit from this change.

else:
print("Post mortem debugger finished. The " + mainpyfile +
" will be restarted")
print("Post mortem debugger finished. The " + mainpyfile +
" will be restarted")


# When invoked as main program, invoke the debugger on a script
