Stale-While-Revalidate or Similar

Hello List,

Is there support for something like "stale-while-revalidate" coming to Varnish?
I need to make the request to my backend-servers async and serve slightly stale content (defined by grace) and I do not want a user to wait for the backend at any time.
Or is there any other way with using vcl trickery to accomplish this?
(Unfortunately I cannot seem to find any info on this topic and the thread I found on the list has not been answered)  [1]
