[Python-Dev] To run all exit handlers or not?

The current behavior of the atexit module is that if any of the exit
handlers raises an exception the remaining handlers are not run.  Greg
Chapman posted a bug report about this:


Greg proposed catching any exceptions and continuing so that all exit
handlers at least have a chance to run and Raymond agrees with him.  I
attached a patch to the ticket to add a flag to determine the behavior on
the principle that atexit has been around long enough that someone out there
probably relies on the early exit behavior.  This is the old Python chestnut
of using a flag to preserve existing behavior as the default while allowing
users to set the flag to get the new behavior.

I'm happy to go either way, but thought perhaps a quick poll of the troops
might be in order, hence this note.
