I agree, "UPDATE during CREATE" and "UPDATE during DELETE" should not be allowed. With the above logic, those actions would only be allowed if no engine responded. Does that make sense to you? When an engine dies in the middle of an action, the stack's state will remain unknown until another action is attempted.
