OK, glad we're on the same page then.  I've had a cold this week and it's been messing with my head.

I think we can treat (3) as a future improvement.  The main benefit is that without special handling for that case what will happen is all GestureScrollUpdates will be sent to the renderer, then sent to the main thread, and the ACK will be held until the render process main thread responds.  This means we can't process any further gestures (or input events at all) until the main thread becomes responsive which might cause jank.  We should try to avoid the main thread whenever we know that we can get away with it.  I agree this needs some work in the chromium side of the world.
