Where the \r and the \n of the Client::MSG_SEPARATOR string appear in separate packets received from a client's socket, this is not currently handled by the Client::dataRecv() method and instead the server appears then to hang, expecting more data from the client.

This pull request allows this edge case to be handled correctly.
