    OK, here is quick implementation of simple quadratic algorithm.
    Seems, it works well on small differences, but fails on big ones.

How does it fail?  By taking forever, or something else?  It might be
faster if you tried using a small bound, then again with the bound
doubled, etc.

I think that computing the distance with a sum would probably be about
as good in practice, and somewhat faster.
