 // Implementation details: We use [NSApplication sendEvent:] instead
 // of [NSApplication postEvent:atStart:] so that the event gets sent
 // immediately.  This lets us run the post-event task right
 // immediately as well.  Unfortunately I cannot subclass NSEvent (it's
 // probably a class cluster) to allow other easy answers.  For
 // example, if I could subclass NSEvent, I could run the Task in it's
 // dealloc routine (which necessarily happens after the event is
 // dispatched).  Unlike Linux, Mac does not have message loop
