I know this is scary, but have you tried renicing them? You might see an immediate worse performance problem (like they can't service queues fast enough), or you may free up the cpu's to do something else. I don't use them, because the whole concept is for scalability, not performance, but if you have a hog, renice could be Jenny Craig.
