Could the truename be saved as a property of the buffer when dired first
visits the directory?

In the case I submitted, I suppose the /net/sfwnv/export/nv buffer (the
one I didn't have permissions for) would be tagged with some error
indicator, rather than the actual truename.

So when dired looks through the existing buffers, it would skip buffers
that have a different truename or an error tag.  Hmm.  I wonder if this
would be a noticeable performance win when the user has a lot of dired
buffers for NFS directories.
