This is a follow up of a feature request which recently appeared on psutil
I don't know whether the proposal makes sense for psutil per-se but it
certainly made me think about multiprocessing.cpu_count() and the fact that
it currently returns the number of virtual CPUs (physical + logical).
Given that multiple processes cannot take any advantage of hyper threading
technology then maybe it makes sense for multiprocessing to expose a
physical_cpu_count() function in order to preemptively figure out how many
processes to spawn.
Same thing is discussed here:
