I'm glad to see I'm not the only one who has noticed this odd
behaviour of nscd. Shame on me for not speaking up sooner, but I
feared I might be proved wrong (again), and yes, that's a lame excuse.

After bulk loading ~250 students into our LDAP (Novell eDirectory)
each fall, and deleting the graduated students, I restart nscd on our
servers just to make sure the caches doesn't contain any negative
results. Maybe I should set up a cron job to restart nscd once a day
until the source code is cleaned up.
