Review comment:
From my understanding I also think it should be fine since it is on
shutdown.

> Currently there is a race where a BundleProcessor doesn't exist until another
> thread picks up the task and inserts into the active set. This allows for
> split/progress calls to happen and error out with "Unknown process bundle
> instruction X".
> Since the control stream is ordered, we can guarantee that an uninitialized
> BundleProcessor exists that can respond to this really early split/progress
> calls.
