Just try compiling the kernel with make -j4 under stock 2.4 and _everything_ in X will be jerky. With the O(1) scheduler things are just as smooth as on an idle system - as long as your application does not get rated CPU-intensive. [which happens too fast in the case you described.] So we do have something in 2.5 that is visibly better in a number of cases, and i want to preserve that - while fixing the corner-cases discussed here. I'm working on it.
