Or possibly one in the NFS server (or an incompatibility between it and
the client), though I don't know the NFS protocol well enough to more
than guess and haven't looked (as you have).

But this class of failure is ancient (pre-Unix!) and ubiquitous, and
is inherent in the conflict between Fortran's file model and almost
every file system interface.  I would dearly like to see not providing
ACTION on OPEN deprecated, but have tried and failed with that one :-(

Thinks:  Hmm.  That's a possible candidate for -Wextra!
