One suggestion I might have is to have python release the global interpreter lock more frequently, you can read about the global interpreter lock here: http://docs.python.org/api/threads.html You might also be able to use some timer/condition construct in combination with this, something like Thread A: if watchdogTimer(): conditionVar.aquire() conditionVar.notify(threadB) conditionVar.release() ThreadB: while(1): conditionVar.aquire() conditionVar.wait() functionToDoSomething() This is pseudo python of course, if you need to know about these objects I would suggest consulting the python manual. -carl -- Carl J.
