I wonder if it would be better/good to use “getconf _NPROCESSORS_ONLN“ or have
it as yet another fallback 🤔️

Anyway, just a thought, no need to update the patch for it.

That's probably a good idea. And since you mention _NPROCESSORS_ONLN, it'd probably make sense to remove the --all argument from the nproc invocation too.
