The problem is that checking the CPU usage is fairly misleading if you are worried about contention. If your process takes up 100% of CPU and nothing else needs the resource, does it matter? I would not want to sleep *unless* something else needs the resource. Of course, there might be a good/easy way of checking usage + contention, but I am unaware of any off the top of my head. On *nix you should just set the appropriate nice-ness and then let the OS handle CPU scheduling. Not sure what you would do for Windows--I assume OS X is the same as *nix for this context.
