/* Run loop one last time (with limit date in past) so that any
* notification about the task ending is sent immediately.
/* Run loop twice more (with limit date in past) so that if the
* notification about the task ending is to be delivered in this
* thread it is delivered before this method completes. (Twice
* because the first time runs the _notifyOfTermination performer,
* which queues the notification, and the second dequeues and posts
* the notification.)
* If the task was launched in another thread, the notification
* is delivered when that thread executes its run loop.
