    This notifier inherits from threading.Thread for instanciating a separate
    thread, and also inherits from Notifier, because it is a threaded notifier.

Note that every functionality provided by this class is also provided
    through Notifier class. Moreover Notifier should be considered first because
    it is not threaded and could be easily daemonized.
