Yeah, possibly. I considered suggesting that the current code be
treated as a fallback implementation of clone_file, but I'm not sure
if there's a convenient way to manage the run-time fallback if we try
to do it like that. In any case, +1 for leaving the door open for
easy addition of other cloning techniques.
