A few at the moment, but they're growing. tail -f, and the l0pht-watch
ports are the only apps I know of at the moment, both of which achieve
dramatic reductions in CPU time (and better performance, for l0pht-watch)
due to not having to spin in poll() or select() when watching the
file/directory. There's also the py-kqueue port which is a kqueue
interface to python.
Brian Feldman was working on kqueueing an ircd which should have good
performance benefits since poll() is apparently a big bottleneck there
too.

I've been tinkering with kq'ing thttpd - in fact I have it working (which
was trivial), although it's not optimized yet so I don't expect major
performance changes - thttpd is still querying each FD individually for
status, instead of just using the next ones kq tells it about. I just need
to figure out how to benchmark it effectively - httperf is running into
client limitations so far.
