> ApplicationContext$ScheduledCallback extends TimerTask and queues a runnable 
> on the UI thread when the timer task is called to run.  This presents a 
> threading problem: the timer task may be called to run (on the Timer thread) 
> while the underlying runnable is running on the UI thread.  In this case, the 
> underlying runnable may call cancel() on the timer task, but since the timer 
> task is currently running, the underlying runnable will be re-queued on the 
> UI thread, meaning that it will get called to run after the timer task has 
> been cancelled.
