I've opened a separate issue (issue 4258) for the idea of using 30-bit long digits instead of 15-bit ones. I'll remove the patch from this issue. Pernici Mario's idea applies even better to base 2**30 longs: one can clump together 16 (!) of the multiplications at once, essentially eliminating the overhead of shifts almost completely.
