They propagate back to the bottom of the callback. If you don't treat
them special, deleting the thread state will also release the
exception object and traceback object. Assuming the thread callback
came "out of nowhere", there is nothing reasonable to do, anyway: you
might want to print the exception to stderr or something like that.
