When a process changes foreground status or dies, NetworkPolicy updates its internal state with a lock held. In cases where there is contention, this can block the AMS handler and prevent other events, such as broadcasts, from being dispatched. This change moves the incoming AMS events to an existing internal NetworkPolicy handler thread, where they can execute without blocking AMS.
