Summary: Comments for why we don't need a lock when updating the SqlIdMap with multiple writers. Structure can definitely be improved but I'll live with this for a short time. No fundamental change in logic. I added extra checks to the insert function and changed from an optimistic insert race logic to a pessimistic version. I explain in the comments that it's to have an easier time reasoning about what happens and that theoretically doesn't matter.
