Version 2.1.3

I'm trying to set Varnish up to use Saint mode and I've noticed that if I set beresp.grace=30s and beresp.saintmode=10s, cache a response and then make the backend fail I'll get stale content served for 10 seconds and then get 503 error responses from Varnish. The backend is still only contacted every 10 seconds.

If req.grace is set to 30s then I get stale content for 30 seconds. Does req.grace have a default value which is causing this behaviour?
