- replace ActorRef.stop() by ActorRefFactory.stop(child) everywhere - ActorCell “optimizes” this to remove the child from its childrenRefs in order to allow immediate recycling of the name - the lost soul must have a place, for which the Locker has been created, where Davy Jones will happily rebind the soul to his ship (i.e. set “parent” to the locker to avoid mem leak) and periodically revisit it (.stop(), in case of that being lost in comm failure, similar .watch() to re-check liveness)
