    Description

      deliverAllHints seems to be a "just in case we miss the onAlive signal to send hints over," but the constant scanning of the hint rows it generates is extremely painful.

      I'd like to do 3 things here:

      1. test that, if node X and Y are in the cluster, and Y goes down, then X goes down, then Y comes back up, then X comes back up [with enough time for each change that FD recognizes it], that X gets deliverHintsToEndpoint called for Y. I think it will, but we should test to be sure.

      2. remove HHOM.deliverAllHints

      3. expose HHOM.deliverHintsToEndpoint to jmx so it can be manually invoked, Just In Case
