Luke Cwik updated BEAM-10959:
-----------------------------
    Summary: Fix race where split/progress calls return "Unknown process bundle instruction"  (was: Fix race where split/progress calls return "Unknown process bundle instruction" since initialization of BundleProcessor happens in a separate thread)

> 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.
