jeez, that's so stupid.  years ago when IBM asked me for input on the
design they were planning to do it right:  cache misses appear in userland
as sockets.

i'd tell IBM the same thing i told sun:  fix your interface.

note that TUX does it right.

you might also want to think about webmux.  'cause i think it breaks some
more assumptions you're making (such as 1:1 mapping between client and
kernel network object).
