[pygtk] Help: Problems with threads and pygtk

[David Hirschfield]

Holy garbage collection, Batman!

That was totally it. Or at least mostly it.
If I surround the actualy processing code in the thread with a 
gc.disable()/gc.enable() pair, the freeze never occurs!

Oy! So, basically that means that even though my thread code wasn't 
actually touching gtk objects, the garbage collection was dumping gtk 
stuff from memory and that was killing things? That's really troublesome 
to me for some reason. But things are working much better now.

Thanks for the tip, have you encountered similar problems before?
