Summary: With BackgroundExecutor+State Reconciliation, it is pretty common to have races where View layer UpdateState calls are thrown away. Theoretically this is /always/ possible since C++ doesn't retry failed UpdateStates, we just try once and then bail. This is part 1 of improving our mechanisms for ensuring that State stays up-to-date from the View layer.
