As I see it, this procedure needs an overhaul anyway. If fstat fails
it returns #f regardless the reason. On IRC we have been comming
to the understanding that we should raise an I/O exception for all
other cases (if the fstat fails for other reasons than the file not
being there).

What does R7RS specify there?
