I don't like the once a second part. Ccould this be checked with
kqueue(2) automatically?

I'm fond of neither "nscd" (Solaris and Linux) nor "lookupd" (Mac OS X).
All of them have given me more (Mac OS X, Fedora Core 3) or less
(Solaris) headache in the past.

The most common problems are:
1.) Overeager caching causes lots of problem.
2.) The name service caching daemon becomes single point of failure.

	Kind regards
