I went back and looked. The OP said no such thing </snip> One of the posters (I thought the OP) mentioned that they were just trying to be a good guy, amidst a lengthy period of intensive CPU usage, of trying to yield occasionally, in the best interests of the system. And the on-point responses were not to worry because time-slicing and WLM etc etc would deal with that..
