    Description

      Discovered while investigating HDFS-1965, it turns out that the reference-counting done in WritableRpcEngine.ClientCache doesn't map one-to-one with open TCP connections. This means that it's easy to accidentally leave TCP connections open longer than expected so long as the client has any other connections open at all.
