Oh, interesting. This points out an implicit assumption I was making,
possibly incorrectly, about the meaning of "finite algorithm". I was
imagining an algorithm running on a finite state machine whose size was
fixed in advanced. You seem to be imagining a Turing-like machine with
an indefinitely long tape that is finite at any given instant, but that
grows as needed by the algorithm.
