Sure, we do:

  onShutdown.add(function() timer.cancel());

But there is more: this timer will likely be cancelled automatically because the
corresponding object is garbage collected. We need to keep a reference to that
timer.

Done.

We already marked the notification as shown at this point. It would make sense
to check the prerequisites first and only call Notification.getNextToShow()
then.
