Yeah, but especially in that case I think it would be nice if the
traceback printed by the system (if all this doesn't get caught at an
outer level) could show both the traceback from the handler and the
traceback that it was trying to handle -- I've had many occasions
where a trivial bug in the handler blew away the original traceback
which was shy enough to make repeating it a pain.
