      Description

      SLIDER-1052's deadlock is triggered by the fact that AMRMClientAsync events are handled directly by AM, and that these events are coming in during AM startup

      If we pushed these into the action queue, they'd be postponed until AM startup was complete (and the queue processing turned on). They'd also guarantee that all events to the AM would get processed in a single queue. We'd need to review it to make sure this doesn't impact the ordering.
