        // Order is important here. There are two concerns we need to handle:
        // 1. We need to avoid a window where a running pod could get onto the Stairway list, but not be
        // on the pod list. That is why we get the recorded list from Stairway *before* we read the Kubernetes
        // pod list.
        // 2. We want to clean up pods that fail, so we start the kubePodListener as early as possible so we
        // detect pods that get deleted. The Stairway recovery method called by kubePodListener works once
        // Stairway initialization is done, so it is safe to start the listener before we have called
        // Stairway recoveryAndStart
