sendfile + non local filesystem + lighttpd = EOPNOTSUPP

[Niki Denev]

This thread seems to relate to the same problem in
dfbsd :
http://leaf.dragonflybsd.org/mailarchive/kernel/2005-03/msg00101.html

I think that this should be fixed, the man page did not mentions
EOPNOTSUPP and this can lead to further confusion because it seems
 that HP-UX for example sets errno to EOPNOTSUPP when the socket is not TCP.

Any comments?

P.S.: It seems like i'm talking to myslef, i hope it's
because it's sunday :)
