Yup - most probable solution, per our overlapping posts, but I don't want to
rush to judgement for pmemd. Whatever we select, of course, if it is
different than what we now have, all our results will change for anything
that uses the rng, which is in some senses everything (since you randomize
velocities following minimization). So there would be a few decisions to
make here.
