I guess haveing a way to invalidate the cache is useful in some
ways. Here we have maildrops in peoples home directories, and
sometimes you get alerted you have newmail, type "inc" and inc
says "no new mail".
A quick ls -l of your home directory fixes this though ;-)
Mind you - still leaves me with the problem that people can read
files they shouldn't be able too.
David.
