> I think the idiom `os.cpu_count() or 1` should be mentioned in the documentation an officially recommended. Otherwise people will produce a non-portable code which works on their developer's computers but not on exotic platforms. And I maintain it's an ugly idiom ;-) Since the user can't do anything except falling back to 1, os.cpu_count() should always return a positive number (1 by default). That's AFAICT what all other platforms (Java, Ruby, etc) do, because it makes sense.
