 That explains why the problem is only seen when checking for primes
 and not elsewhere (where all numbers are big).
 Since this occurs with both the old and new [Mod]Pow I suspect the
 problem is in the multiplication (with modulo) code.

+Hey, thanks for the couple of fixes :)
+BTW Kazuki reported that it takes about 6 seconds (at his box) when
+the arugment is 65537. Probably it takes too much.
