I agree. I'm not sure whether NFS guarantees we see the latest data
when reopening read-write (cached pages will be left on the
destination host from the initial read-only access).
AFAICT the re-open has to re-validate the metadata. If ctime has
changed since the previous stat, the client has to drop local caches.
