Funny thing is that relational databases will lock on things whether or not the calling code is using an async system. Locks are a necessary thing in many cases. That lock-based concurrency code can’t be mathematically proven bug free doesn’t detract from its vast usefulness in situations that are not aeronautics or medical devices.
