and thread unparking.\r\n\r\nThis PR partially reverts some changes from earlier scheduler optimizations and fixes a case where if multiple concurrent schedule() calls happen, the order in the SubscriptionList might be different from the actual execution order which degrades performance on task termination due to remove() being O(n).\r\n\r\nThis might be the source of degradation in #2857
