I understood from Tom's last mail that the messages are being constructed *in kernel memory* before sending out of the tcp socket. What advantage gives sendpage? The message construction must actually happen before to fill in the necessary headers for the length, so receiver can dissect again. Streaming semantics don't really fit here?
