I know that I'm not answering your question, but I thought I might
throw in some advice, if you have a need for speed.

It would be much faster to create an Vec3Array type object, and do the
loop iteration with the += operating inside C++. This would make your
Python API look something like:

positions = Vec3Array(10000)
velocities = Vec3Array(10000)
positions += velocities

Also, Stackless will have little effect your benchmarks, so you may
find more answers in a more general forum.
