/**
* The Notifiable class is an interface that may be used in the application. It provides
* a single callback (notify) that is invoked when the agent or console has events to be
* handled by the application.
*
* This interface should only be used in an application that has more event drivers than
* just a single QMF interface. For example, an application that already uses select or
* poll to control execution can use the notify callback to awaken the select/poll call.
*
* No QMF operations should be performed from the notify callback. It should only be used
* to awaken an application thread that will then perform QMF operations.
