KAFKA-3378; Client blocks forever if SocketChannel connects instantly This is a different implementation to the one in #1085 by Larkin Lowrey (@llowrey). The hard part here was actually finding the problem and all credit goes to @llowrey. This PR also changes fixes our handling of `finishConnect` (we now check the return value).
