Responses to layout queries are just sent messages (if layout needed invoking to answer them). It is possible to send them early as soon as the relevant data has been computed. Servo does not do this currently though. An initial implementation could just reply with the answer and then keep running layout to completion. I assume this will still require styling + 2 tree passes in most cases, but the last pass will be shortened.
