You could use PyThreadState_SetAsyncExc - it's supposed to raise an  
exception in another thread. There is a Cookbook recipe using it here  
<http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/496960>
I've never actually used it, but I want to try it some day, so please  
report back your findings if you decide to use this function.
