+/**
+ * Queue handler for letting plugins handle stuff.
+ *
+ * The plugin queue handler accepts notices over the "plugin" queue
+ * and simply passes them through the "HandleQueuedNotice" event.
+ *
+ * This gives plugins a chance to do background processing without
+ * actually registering their own queue and ensuring that things
+ * are queued into it.
+ *
+ * Fancier plugins may wish to instead hook the 'GetQueueHandlerClass'
+ * event with their own class, in which case they must ensure that
+ * their notices get enqueued when they need them.
