> Currently, if a client connects to a DN and begins to read a block, but then
> stops calling read() for a long period of time, the DN will log a
> SocketTimeoutException "480000 millis timeout while waiting for channel to be
> ready for write." This is because there is no "keepalive" functionality of
> any kind. At a minimum, we should improve this error message to be an INFO
> level log which just says that the client likely stopped reading, so
> disconnecting it.
