I think it should be possible to achieve the same result with sendfile()

Yay, more #ifdef's!
That's not my problem, I'm just suggesting ideas. ;-)
Hm, I am wondering if that's a win; that means two extra syscalls.
Here two extra syscalls (a few microseconds nowadays?) can save processing
a packet (or more), and incurring network latency (a hundred microseconds
on my Ether).
We could play some games if you're sending a large chunk of data,
though ... you would only need to set TCP_CORK at the beginning of
sending a large chunk, and clear it at the end. Clearly plenty of
things to play with.
This is exactly how it's meant to be used.
