Description:
 def step(self):
 """Grab a new message and dispatch it to the handler. This method should not be extended or overwritten. Instead, implementations of this daemon should implement the 'get_message()' and 'handle_message()' methods. """

        message = self.get_message()
        if message is None:

            self.sleep(self.idle_time)
            return None

        self.dispatch(message)
        # In non-greenthread environments this does nothing. In green-thread
        # environments this yields the context so messages can be acted upon
        # before exhausting the threadpool.
