> When we stop a stateless flow, we have a situation in which we stop all
> instances. However, they currently share the same LifecycleState object,
> which means that after the first instance terminates processors, all
> subsequent instances fail to call the Processors' @OnStopped methods,
> throwing a TerminatedTaskException when attempting to increment the active
> thread count. This is not obvious in the UI but shows in the logs, and it
> results in not properly handling the closing of resources.
