Hmm, I think that's a false economy on brain cycles. A variable called
nr_cpus that isn't a number of CPUs is bound to waste a bunch of
mental energy at some point in the future.

Unless you strongly object I'll go for nr_parallel. It's not a great
name but, well... I think that probably just suggests it's not a great
variable, and I don't have time to fix that.
