So there are two things here.

One is that if we know that the actor is terminated, then we can just skip trying to set it , since the throttle settings will be picked up when a new connection attempt is made.

The second is the race between ask and and termination, which I think would be ok with a smaller timeout and a recover. We basically assume that if we haven't heard from him in X, he must be dead, and the settings will be picked up by the new connection attempt.
