And that, of course, is the best procedure. Locking/unlocking the screen 
works on sort of a reference-counting approach. In general, locking the 
screen increments a counter, unlocking the screen decrements it. When 
the counter reaches zero, the screen is unlocked and all the pending 
updates take place.
