Snippet From: http://wiki.apache.org/cassandra/Operations#Token_selection

	If nodetool repair has not been run often enough to the point that GCGraceSeconds has passed, you
	risk forgotten deletes (see DistributedDeletes). In addition to data popping up that has been deleted,
	you may see inconsistencies in data return from different nodes that will not self-heal by read-repair
	or further nodetool repair. Some further details on this latter effect is documented in CASSANDRA-1316.
