(Quorum?)

In either case (quorum *or* quota), fencing is still required, as there's no
assurance that a rogue node can't flush buffers.

Fencing *forcefully* prevents nodes from flushing any outstanding buffers to
disk after we've declared them out of the cluster, regardless of the
membership/quorum model used.
