Hinted Handoff Burning lots of CPU cycles

                 Key: CASSANDRA-883
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 0.6
            Reporter: Chris Goffinet

We've noticed on 2 clusters already, when HH CF gets data, it looks to be looping over and
over again on both HINT DELIVERY and HINTED-HANDOFF-POOL. Both threads in top show over 90%
cpu. No nodes have been added/removed lately. I also did a major compaction on HH just to
be sure.
