    but his example fcloses a file which was not opened. This isn't "further
    access".

    Is it difficult for Linux to spot the the file isn't open and return EBADF?
    What does POSIX have to say about this? IMHO making it easier to port your
    programs to Linux (and behaving a little more sanely :) is worth a couple of
    extra bytes of anyone's kernel.
