Yup. My troubles came when I had a handler unlock the screen 5 times straight and I do not lock the screen to that many levels. It still did no unlock the screen, so now it may be that one handler cannot unlock another handler's lock screen, which I was unaware of.

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.
