[yocto] Shorter build time?

[Takashi Matsuzawa]

By the way, PyPy seems to have some restriction that is not fully compatible with CPyhon and bitbake scripts may not run as they are.  I tried it yesterday and learned that it is not a simple in-place replacement.

That is true, but I've seen cases where the start up time of Python (or
the time it takes bitbake to start "doing work") is *perceptually* much
larger than the work done by the recipe, or at least it looks like it
represents a sigficant fraction of the total work. That's where PyPy
might help.

Measuring that overhead should be fairly simple, and if it's true then having a pool of workers would be a good optimisation.
