Right, you are just make process sleep instead of processing events.

There are number of ways to do it. The closest to your current
implementation is usage
of gobject.timeout_add but probably it also may have sense to emit
signals in your threads
when they finish tasks and in main thread just connect to signal. 

www.pygtk.org has a number of tutorials that may help you with this kind
of question.
