ScreenSaver: Timeout if window won't lock. Fixes #4260.

If we fail to lock the window in the kInitialTickRate time, quit the thread. We were deadlocking causing #4260 because you could open several threads by moving through the screen saver list quickly all trying to lock the same window at the same time, classic deadlock.
