Probably, but it might mean they were no longer thread
safe. An exception caught and raised in one thread would
be vulnerable to having its traceback clobbered by
another thread raising the same instance.

There's also the possibility of a traceback unexpectedly
kept alive causing GC problems -- cycles, files not
closed when you expect, etc.
