_dispose(): A bit of elaboration so that we can properly

RegisterBounce on known permanent failures.  These are handed to us
via the exception object when SomeRecipientsFailed is raised.  Append
any permanent failures to an instance variable to be handled in the
_doperiodic() method.

Temporary failures are still handled the same way, except we only
requeue the message if we've actually got temp failures to retry.

_doperiodic(): Periodically, we attempt to acquire the list lock and
register all permanent failures we've got pending for that list.
