As opposed to a dedicated work queue for both combined? I had a
separate queue in an earlier patch, but dropped it while debugging some
other stuff. We should bring it back to ensure ordering. That would
remove the need for a few of the syncs, and would also let us queue a
check at the appropriate time on the same queue.
