An inode still has uid, gid and permission information, so the files aren't
completly unprotected.
A far bigger problem in real live with this patch is that it doesn't really
help to speedup things like unlinking files, therefore it doesn't help to
speed up the expire. As I said, a good kludge but no real solution.
