> I was running testbackupnode and noticed that NNprotocol proxy was not being closed.
Talked with Suresh and he observed that most of the protocols do not implement ProtocolTranslator
and hence the logic in stopproxy() does not work. Instead, since all of them are closeable,
Suresh suggested that closeable property should be used at close.
