I think this is a good idea.  Poking around file descriptors to
see what they are connected to just doesn't agree with UNIX
philosophy.

I would also suggest that all UNIX special files, not just
/dev/null, shouldn't be checked.  I think they are outside the scope
of the Fortran standard, because they violate Fortran semantics
(like being able to read back what you wrote for /dev/null :-)
