I have a little pattern, or idiom that I use on many threads.  
I like to wait on the threading 'Event' object rather than the 'sleep'
timer, because it gives me the ability to break out without waiting
for the full interval. 

import threading

class QQQ(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self, name="QQQ")
        self._stopevent = threading.Event()

    def run(self):
        while not self._stopevent.isSet():
            # do some stuff
            self._stopevent.wait( s )

    def join(self, timeout=0.0):
        self._stopevent.set()
        threading.Thread.join(self, timeout)
