I wish PyPy supported multiprocessing. It does theoretically, but imposes a significant penalty, so it's not in a practically usable state.

That's from almost 3 years ago. Have you ran the attached patch to check the benchmarks with a more current release? I don't know if that's been fixed, but it probably wouldn't take much time to test out.

I last tried my own code which uses multiprocessing a few weeks ago. If anything, it gets slower with each release.

Is this the same case with threading (like multiprocessing.dummy)?
