I had the throttle closed (engine to idle not stopped) for me, on the downwind leg, twice today. The delights of the biennial reval flight. Both times I modified the circuit shape/size and got onto the ground without resorting to more throttle. It wasn't tidy but it was effective and I still had the aircraft to fly home afterwards. I do love side slipping and generally chucking it about at low altitude on approach. It is easier to rescue an overshoot than an undershoot so I always aim high. I do wonder how much difference a stopped engine would make things but I am not ready to try it into a 380 metre strip.........
