for anybody interested.  i'm not sure this qualifies as the "right" way to
do aio, but it would certainly help the case of accessing a raw disk... it
doesn't really touch upon dealing with a filesystem, and it only briefly
touches upon joining two udp sockets, but makes no mention of tcp.  ubc
also makes this a tougher proposition since the pages just get faulted in
rather than brought in via bread() or breadn()...

is that the paper you were thinking of, thor?
