Help out with a data point? Are you running KDE as well? If you are, then it looks like the common denominator that RSDL is handling poorly is client-server communication. (KDE's KIO slaves in this case, but X in general.) If so, one would hope that a variation on Linus's 2.5.63 pipe wakeup pass-the-interactivity idea could work here. The problem with that original patch, IIRC, was that a couple of tasks could bounce their interactivity bonus back and forth and thereby starve others. Which might be expected given there was no 'decaying' of the interactivity bonus, which means you can make a feedback loop. Anyway, looks like processes that do A -> B -> A communication chains are getting penalized under RSDL. In which case, perhaps I can make a test case that exhibits the problem without having to have the same graphics card or desktop as you.
