If this boolean is false, the port is recycled, thus leaving clients to remain oblivious to the demand nature of job. If the value is set to true, clients receive port death notifications when the job lets go of the receive right. The port will be recreated atomically with respect to bootstrap_look_up() calls, so that clients can trust that after receiving a port death notification, the new port will have already been recreated. Setting the value to true should be done with care. Not all clients may be able to handle this behavior. The default value is false.
