* A KeepAlive connection is not physically closed immediately after the close,

*
* This interface is implemented on a stub. It allows to have a #close function in a master
* client.
*
*
This class is intended to be used internally by HBase classes that need to make invocations
* against the master on the MasterProtos.MasterService.BlockingInterface; but not by
* final user code. Hence it's package protected.
