Forget the first argument - it just happened to be an accident: As I am on 12.04 beta, there seemed to have been something fixed --before-- I recompiled R (I did it on both machines at the same time - unfortunately). And the speed results turned out to be better due to other causes. But the second point remains: revolution-mkl makes R stall under some circumstances (e.g. using mclapply from the parallel package).
