So ideally we'd reduce the number of special cases instead of increase them. Does this patch make an actual difference, if so how much and with what workload? Also, I suppose that if we finally manage to parameterize the whole load-balancing to act on: nr_running/util/load depending on the domain this all naturally falls into place.
