Thanks, Peter!
At a first glance, your main patch does not look much smaller than mine, and I thought the whole point of re-doing it was to throw away extra features and make things smaller/simpler...
Anyway, I'll test your patchset over the next week or so and let you know if anything really needed is missing (other than waking an idle server if there is one on a worker wakeup; this piece is definitely needed).
