Asyncore seems to be based on fundamental assumptions that aren't true
for non-blocking ssl sockets.  After looking into it for a couple
hours, the way you use ssl with asyncore is like this:

    pid = subprocess.Pipe(["stunnel","stunnel.conf"]).pid
    # insert asyncore app here
    os.kill(pid,signal.SIGTERM)
