> 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.
