My reluctance was due to the need for libgmp. If it is needed elsewhere 
and hence "free" for BBS, then I think the latter is clearly worth 
keeping. In principle, it even ought to be a better choice than Mersenne 
for interactive play.

All this discussion is for play, by the way. In the original post on the 
subject, Ian mentionned simplifying rollout export data ; for rollouts, 
Mersenne is the most (the only ?) sensible choice and we could use it 
exclusively and drop the "set rollout rng" setting.
