def beforeDaemonize(self):
        # Twisted-internal method called during daemonization (when application
        # is started via twistd). This is called right before the magic double
        # forking done for daemonization. We cleanly close the kqueue() and later
        # recreate it. This is needed since a) kqueue() are not inherited across
        # forks and b) twistd will create the reactor already before daemonization
        # (and will also add at least 1 reader to the reactor, an instance of
        # twisted.internet.posixbase._UnixWaker).
