There has to be a way around dealing with the NFS case. It's surely
quite common - certainly it's one I have to deal with a lot.

That said, it's maybe something to solve in the NFS code better, as I
often resume from suspend to a different network and only really notice
my old NFS mounts are still there when I try to use a file->open dialog
which just hangs (as does e.g. "df") if you have such stale mounts and
never seems to recover.

Either way, some better way of handling of this really needs to go in
somewhere in the stack!
