Well is that what this nice/rt thing does? When I was looking to see if the code was already in the kernel I was kind of paying attention to what it appeared to do...kind of. It seemed to me that it was all set up so you could just increase the priority of tasks and tell the kernel they don't have to be as nice to other programs and not to necissarily pre-empt them. I would think that it might be beneficial to just up a program's priority a touch or maybe lower its nice level a touch so it might run a little smoother at the expense of other programs. Does a program on a system with a kernel with the nice-rt 'patch' need to know about rt scheduling?
