I know. The part which gets easily forgotten is that sendfile() as
special purpose interface is not replaced by that -- since it can
directly interact with the VM cache, it can more intelligently decide
how to "lock" the affected memory range.

that's okay, I just pointed out to a concept that seemed related to what you guys were talking about.. a "generic zero-copy syscall that does for any file descriptor instead of just for file -> socket" .. or has "corecode" said: sendfile for sockets... :)

something like that...
