...except, in addition to the DMFS file system, a compressing file system
might want this, as might an encrypting file system. Basically, you'd
add it in more than one place, so why not let a generic file descriptor
attribute do the trick, especially one you can set when you open the
(Note, you want ALT_IO _per file descriptor_, not per file).
