No particular reason other than that I wanted to experiment with the priority of the kernel threads when we test it under heavy load. If all these are deemed necessary, I will clean it up. There is one minor irritant - I need to check if the worker thread for my cpu is running or not. I will have to add something to do that since this whole thing is conditional and also RCU is initialized before workqueues.
