Pacemaker adds the drop-in just before it starts the resource, and it 
removes the drop-in just after it stops the resource. It's entire purpose 
is to handle the case when Pacemaker and the service are *simultaneously* 
stopped (i.e. by something external to Pacemaker).

Without the drop-in, what can happen is that the service is stopped before 
Pacemaker thinks it should be stopped... which makes Pacemaker attempt to 
recover the resource... which makes every go wrong quickly.
