> In BlockingChannel, we had the following code to log the actual socket buffer 
> size when the socket connection is established. This can be helpful when 
> tuning the socket buffer size for long latency network. It would be useful to 
> add that in Selector.pollSelectionKeys when the socket is connected.
>         val msg = "Created socket with SO_TIMEOUT = %d (requested %d), 
> SO_RCVBUF = %d (requested %d), SO_SNDBUF = %d (requested %d), 
> connectTimeoutMs = %d."
>         debug(msg.format(channel.socket.getSoTimeout,
>                          readTimeoutMs,
>                          channel.socket.getReceiveBufferSize, 
>                          readBufferSize,
>                          channel.socket.getSendBufferSize,
>                          writeBufferSize,
>                          connectTimeoutMs))
