My understanding is that isn't really preemption, rather it's cooperative scheduling. As soon as the scheduler hand execution to the actor, everything else in the system has to hope there isn't a bug in the actor that permanently ties up that thread.

Good point. I guess I find it like a hybrid where you don't benefit from the cooperative side and don't achieve true preemption. I think either end would be better than keeping the middle ground.
