> Earlier, run-queues could have empty queues or queues for which exclusive
> locks are already taken. Thus poll() on table/server run-queue might have
> returned a Queue which didn't have any valid procs to run.
> With wait/wake on exclusive locks doing {removeFrom|addTo}RunQueue and poll
> removing queues when last element is removed, i think we can remove this
> function now.
> (am finding these things when working on a larger patch, but there are
> changes like this which seem too critical to mess up, so am creating smaller
> focused patches for them).
