Details
Pre-barriers are used to ensure correctness of incremental marking. We do not run them during major GC finalization as this is not required. Nursery collection may also call finalizers however (e.g. for Map/SetObject) and this may call prebarriers. I don't think this is required for correctness and if not we should disable them to help performance.
