Ah, now I looked at the Linux manpage of sendfile and I understand a bit
better. BSD sendfile is _much_ more convenient; it is zero copy, the
special case of count = 0 means "all the data there is", and it has
additional argument that makes it possible to string multiple buffers
a la sendmsg. I have assumed the Linux one was a clone, while in fact
the splice proposal looks more like BSD sendfile.
