The computation processes in Erlang might be serving other processes, so they can't be stacked in one scheduler getting lower effective priority. But the "tasks" in Cilk are working together to complete a whole computation, so the scheduler just needs to keep every core busy to make the computation finishes fast. 

Spot on. The two systems have different goals. So naturally, their implementations are different.
