My turn to chime in.

- Reiterating the fingerprinting problem that's already been mentioned that we have no response to.
- "Number of physical cores" does not correlate to the number of simultaneous tasks supporter
- "Number of physical cores" does not correlate to computing resources currently available.

There modern approach to "let me do as much work as possible without hindering overall performance on the system" that at least some systems support.  Grand Central Dispatch on OS X, for example, will executed more tasks simultaneously when the resources are available but scale back when other apps demand some resources.

Is there a real problem that having this bit available would solve that couldn't also be solved by a GCD-style mechanism?
