Actually, NFS already has a private scheme precisely because of the
page_symlink 'brokenness'.

Are you serious about the uid indexing thing though? It'd be dead easy
to implement, but do we really want something like this in generic NFS?

Personally, I would have thought that a mount option to turn off
caching of readdir/symlinks/... would be a better solution for those
few cases that need it.
