In netcdf-3, the ncid is the underlying file descriptor, so in
most cases, the first ncid returned is 3, the standard Unix behavior.
Evidently the Cray I/O system returns a larger file descriptor for
some reason, but it shouldn't cause any problems, as long as you just
treat is as an opaque handle to the file.
