For server machines.  For laptops, these events happen more often.
However, for most laptops, the rate that they happen is typically on
less than 1/hour.  Still rare enough to not worry about optimizing it
and your other points are good.  I just wanted to make sure that it
wasn't optimized to the point where disconnecting the cable from the
laptop to move it accross the room, or another room doesn't cause huge
problems.
