Review comment:
You'll want to differentiate the failed case and once the Go SDK handles
bundle finalization consider that as well (i.e. keep INST live until the
finalize request comes or a user specified timeout happens)

> 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.
