The question many will ask is it worthwhile to do this? A missed factor doesn't really impact GIMPS much (and certainly won't result in a missed MP). But I think there may be some interest in this ability (if it isn't too computationally expensive -- the second runs could be a random distribution).
Elsewhere he mentions an overhead of under 5%, perhaps 2-3%, seen in his testing of it, compared to unmodified mfaktc. That's without any spot-check duplicate runs.
