That's the way the interface is supposed
to work, and indeed it does do that. However,
as I said, it's slower than the read/write
path.

I posted a version of the kernel patch
to implement recvfile to the kernel
mailing list - got rejected of course
(but it wasn't very nice code :-). If
you want to fix that up and get it upstream
many people would be very happy with
you :-).
