    pkey = None
 
    p = Pyrowl()

    if os.path.isfile("myproviderkey"):

        pkey = open("myproviderkey",'r').readline().strip()

        p.providerkey(pkey)
 
    p.addkey(keys)
 
if __name__ == "__main2__":

    if os.path.isfile('myapikey'):

        keys = filter(None,

                      open("myapikey",'r').read().split("\n")

                      )

alarm2 only asks for input once and then exits. It might also be a problem with the use of global armed. I use multiprocessing, not threading, but the threads may not communicate so changing something in one thread is not recognized in the other. It retains the value first passed. See Signaling Between Threads on Doug Hellmann's site as a place to start.
