[Bug-gnubg] Parallel dice streams

[bob koca]

 I want to compare the effects of score on a doubling decision for a checker position. So I want to rollout

1296 times at two different scores. To hopefully lower variablity for the differenceI used the same seed for each rollout.  Does it mean that the dice will be the same for each game

(until one ends of course)? So the 1rst, 2nd, 3rd, ... games have the same dice. Or does it all get messed up as soon

as one game for one rollout takes longer than its counterpart in the other? I thought it should be the former but a short testing of it

(7 rollouts for each with seeds 100, 200, ... 700) does not show a  strong positive correlation like I would have expected.
