Cool :) I have updated the zip and CPUID is now public domain. There is 
one more thing (at least) that should be implemented though before this 
is really worthy of being in std (IMHO).

The threading info is only probing the hardware. The OS might not allow 
the app to use those resources so processor affinity stuff should be 
added. I can add this, just have to read up on it. Or if someone knows 
it already feel free to patch, in which case I will do nothing :P
