	 * - The tevent timer
	 * - The tevent context
	 * - The Python context -- "self"
	 * - The Python timer (TeventTimer_Object) -- "ret"
	 * - The Python callback function -- "callback"
	 *
	 * We only use the Python context for getting the tevent context,
	 * afterwards it can be destroyed.
	 *
	 * The tevent context owns the tevent timer.
	 *
	 * The tevent timer holds a reference to the Python timer, so the Python
	 * timer must always outlive the tevent timer.
	 * The Python timer has a pointer to the tevent timer; a destructor is
	 * used to set this to NULL when the tevent timer is deallocated.
	 *
	 * The tevent timer can be deallocated in these cases:
	 *  1) when the context is destroyed
	 *  2) after the event fires
	 *  Posssibly, API might be added to cancel (free the tevent timer).
	 *
	 * The Python timer holds a reference to the callback.
