Please send me any patches you want considered.  However, sleeping
backends is something I've never done nor intend to do.  That is all
Chris Murdoch's logic and I usually try to avoid it.  IOW, you all are
now probably more versed in it than me.

FWIW, I'd very much like the sleep and wake logic to be moved
completely or mostly out of the scheduler proper and into some other
component which observes the schedule and acts accordingly.
