> {{DirectMessageWriter#writeHeader}} writes the message header as two
> {{short}} values. This may result in problems, when the outgoing buffer only
> has less 2 or 3 bytes left, in which case only one {{short}} value will be
> actually sent. Current code does not handle this situation properly, so it
> will send the whole header again, despite that the first two bytes have
> already been transferred to the receiving side.
