I'm not a wxPython user, but what I've heard is that it tries to
write stderr to a regular window within the process. Crashing
apps vanish from the screen, taking their error windows with
them. Most any GUI toolkit has to return to its event-loop
before it will update the screen, preventing it from showing
messages of fatal errors.
