I'd be +0.5 for multiprocessing because:

...but my main concern was first figuring out whether it might actually make sense to distinguish between virtual and physical CPUs in a real world app.
I would go one step further and expose the topology of the CPUs. It's much, much more complicated than just physical and logical CPUs.
I'm not sure what the point would be. From the point of the view of an application programmer, the CPU topology is an almost esoteric detail. This would be appropriate for a third-party "system information" package, IMO (with memory speed, number of PCIe channels, cache associativity, etc.). Regards Antoine.
