Just a triggered thought: I am wondering if Conway's Game of Life http://en.wikipedia.org/wiki/Conway%27s_Game_of_Life might be be an interesting/fun basis for experiments and maybe a benchmark for STM use in the parallel update of the life grid.

I am thinking of in-place update, since old-frame -> new-frame would not create any conflicts.

I suppose the boring answer is that old-frame -> new-frame looks more natural. Even if not, I can think about different answers, but it doesn't seem that STM as I think about it is really related to them. STM in PyPy is merely an "implementation detail" to speed up a GIL-like user experience. Armin
