It's useless, sendfile(2) is a win when you have to copy something
straight from disk to the network.
BTW, it's probably a good idea to use TCP_CORK to send out the 220 line
and the beginning of the article in the same packet.

In these situations you just use write(2) or writev(2), sendfile(2) may
actually be slower.
