 The purpose is to allow a major compaction or repair to be run on a node that is under too
much load for this be safely done "live".  Marking a node as down by disabling gossip is good
enough in some cases(for major compaction).  But for repairs is insufficient, since hints
will build back up once I repeat the process on the next node.

 I am also concerned of the effects of having different numbers of nodes available for write
and read quorums.
