By the way, one thing that makes me nervous is that we lack an
explicit "request queue" or "per-queue" concept. State can either be
per-BlockDriverState (shared state) or per-request, but not per-queue.
So far there hasn't been a need for per-queue state but there may be
opportunities to eliminate locking if we can replace shared state with
per-queue state.
