The code to tell the lower layer to enable or disable watching for
certain things was lazy in disabling, it waited until a timer tick
to see if a disable was necessary. Not a really big deal, but it
could be improved.
Modify the code to enable and disable watching immediately and don't
do it from the background timer any more.
