> The AM queue executor goes live before AM startup; if external events come in (e.g. container completion reports), they aren't handled right. This is a re-emergence of a sync-startup problem seen before on restarted containers, as container completion comes in before cluster state buildup complete. Despite the sync block around app state, the extended AM is vulnerable to the same race condition.
> Fix: don't start the queues until the last moment...the events will just get scheduled awaiting that moment
