I spent some more time on the prevent-unnecessary-wakeups patch for
logical/worker.c that I've been alluding to in this thread, and I found a
few more places where we depend on the worker periodically waking up. This
seems to be a common technique, so I'm beginning to wonder whether these
changes are worthwhile. I think there's a good chance it would become a
game of whac-a-mole.
