There was a bug in setting affinity of a thread that assumed affinity from lookup table with key being a thread name. When names was appended with consecutive numbers (e.g. "RenderingThread 1") the mechanism failed. Refactored this to use special static consts describing affinity override'able by different platforms for different affinity types + possibility of setting affinity per thread.
