You know, you're right.  I'd been thinking (not-very-clearly) that 
registering the callback would keep the reference alive until it was 
called, guess I'm too used to PyDispatcher's operation.  Urgh, that's 
seriously annoying, requires storing the callback somewhere external.

Back to __del__ I suppose.

Thanks Alex,
