+/*
+ * Some background:
+ *
+ * Originally, there was a "StandbyStateChangeNotifier" that belonged to policy-core, and this class's handleStateChange() method
+ * used to take care of invoking conn.standDownPdp(). But testing revealed that when a state change to hot standby occurred
+ * from a demote() operation, first the PMStandbyStateChangeNotifier.handleStateChange() method would be invoked and then the
+ * StandbyStateChangeNotifier.handleStateChange() method would be invoked, and this ordering was creating the following problem:
+ *
+ * When PMStandbyStateChangeNotifier.handleStateChange() was invoked it would take a long time to finish, because it would result
+ * in SingleThreadedUebTopicSource.stop() being invoked, which can potentially do a 5 second sleep for each controller being stopped.
+ * Meanwhile, as these controller stoppages and their associated sleeps were occurring, the election handler would discover the
+ * demoted PDP in hotstandby (but still designated!) and promote it, resulting in the standbyStatus going from hotstandby
+ * to providingservice. So then, by the time that PMStandbyStateChangeNotifier.handleStateChange() finished its work and
+ * StandbyStateChangeNotifier.handleStateChange() started executing, the standbyStatus was no longer hotstandby (as effected by
+ * the demote), but providingservice (as reset by the election handling logic) and conn.standDownPdp() would not get called!
+ *
+ * To fix this bug, we consolidated StandbyStateChangeNotifier and PMStandbyStateChangeNotifier, with the standDownPdp() always
+ * being invoked prior to the TopicEndpoint.manager.lock(). In this way, when the election handling logic is invoked
+ * during the controller stoppages, the PDP is in hotstandby and the standdown occurs.

+ * does not create a new instance, it will force it to go through an initialization
+ * cycle which includes a "pause" at the beginning of proecessing. We just must
