If one uses M4RI with the new patch from within Sage another PRBG is used, but coinflip should be fine. Don't see these speedups (but I have two Gray code tables and this warrants for more if's) Hi, I think we might consider merging our two forks again? Or do you also have the two Gray code tables? Are your timings on the Opteron? Because then things look really goo since mine are on the C2D.
