The way i would do this is by using an threading.Event (
http://docs.python.org/lib/event-objects.html )

<code>

class eventhandler(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self)
        self.event = threading.Event()

    def run:
        while True:
            # block until some event happens
            self.event.wait()
            """ do stuff here """
            self.event.clear()

</code>

the way to use this is to get the main/separate thread to set() the
event object.
