Solve the following python programming problem given the following code:
def startTimeoutThread(timeout) : 
    "
    Start a thread which will eventually kill the process if the tests aren't finished
    after the timeout
    " 
    assert (t is not None) 
    def killer() : 
        time.sleep (timeout) 
        (print >> sys.stderr) 
        ((print >> sys.stderr), (' *** Test failed to finish in %s seconds, aborting *** ' % timeout)) 
        ufora.native.Tests.forceStackdump () 
t = threading.Thread (target = killer) 
    t.daemon = True 
    t.start ()
