Re: server won't exit when a streaming connection is active

add an asyc signal handler. something lie this should work:

def sig_handler(signum, frame):
    Stop()  # your Stop() function

# register the handlers before you call your  Start(), eg.:

signal.signal(signal.SIGUSR1, sign_handler)
signal.signal(signal.SIGUSR2, sign_handler)
