FWIW, I'll umpteenth the motion to do this. I'm tired of reinventing the
hack I did for DVS way back when where they moved data off of cache disks
into large statically allocated kernel buffers and used mmap to get at
them from User space, tweak some appropriate bits and then ship them out
via UDP- all to avoid the extra bcopys because there wasn't a notion of
direct I/O to user space.
