It turns out that a few workloads (easyWave, fio) have a fairly low success rate on newidle balance, but still benefit greatly from having it anyway. Luckliky these workloads have a faily low newidle rate, so the cost if doing the newidle is relatively low, even if unsuccessfull. Add a simple rate based part to the newidle ratio compute, such that low rate newidle will still have a high newidle ratio. This cures the easyWave and fio workloads while not affecting the schbench numbers either (which have a very high newidle rate).
