Before I go ahead and actually write something again how about a
consensus on where this negative cache should be?  I don't think the
dnlc currently supports caching negative information (the comments say
that anyway) but that shouldn't be too hard to fix.  Caching negative
entries in afsd would be easier of course.

I would probably like to be able to examine and purge this cache as
well.  This would be sort of vile since it would likely be part of fs
and have to go down to kernel and back up to afsd if negative caching
in afsd (unless we want to do something else like a unix domain socket).

Anything else?
