amicable.sage does not exit cleanly

[daira]

Eventually all of the worker threads hang, whether or not any acceptable curves are found first. It should exit when it has exhausted the search space.

If we are selecting the first solution, why not exit after displaying that exact solution?

Wouldn't this complete faster and be less ambiguous?

Do we want to examine other solutions for any reason? If so could we add an --exhaustive | --first set of cli alternatives?

When I opened this ticket we did not have a need to pick the first solution. I agree that a --first argument might be useful, and that it would work around the bug in cases where we know there's a solution. It doesn't fix the bug, though; we should exit when we've exhausted the search space regardless.
