I don't believe there's a setuid program involved, but in any event, in
the NFS configuration for my diskless workstation, root does in fact
have privileges over NFS, so that can't be what's going on.

Besides, the failure is intermittent.  It's truly bizarre.  All I can
think of is something to do with, perhaps, stale NFS file handles and
fd passing or inheritance...
