Do not kow of this happening in any twin jet. I would suspect the use of drag in any form but would not worry about flap or gear overspeed limitations. Chop the overspeed engine at a low altitude, using aerodynamic breaking, better to steer off or run off the runway than landing short due to crytical miscalculation of glide expectations in an emergency.
RWY's like at JFK with over run retardent materal are great for scenarios like this.
