It looks like you are just taking the mutex around various of_changeset_* calls. We should either split the mutex into of_mutex for core and changesets and an overlay mutex for overlays, or we need to do the typical pattern of having changeset functions having locked and unlocked versions for external and internal (overlays) use.
