Well, we're pretty much scraping the bottom of the bucket, here, in that
there are only so many places that the non-existence of a directory
dentry could be recorded. The only other thing that comes to mind as
potentially interesting would be to see what objects in /afs are
indicated as in use by lsof(8), after both 'echo 2 > /proc/sys/vm/drop_caches'
and 'fs flushall'.
