Version 2b still fails on http://factordb.com/index.php?id=1100000003606729924. Version 3 works. It's about 2.5x slower on that number, but still almost 6x faster than GMP at that size.

Please make use of gwnum optional with an option to configure. The current code supports Arm and we shouldn't break that.
