I don't know what happens in reality, but in an approved/certified simulator it was all over in less than two seconds. Not just the roll but the crash as well.
Fortunately that one had a reset button.
Of course in a non-moving sim you don't have the seat-of-the-pants feeling of the tremendous yaw that an engine failure would cause, so that may dull your reflexes a bit. On the other hand the yaw also doesn't wipe you off your seat so you can still access all the controls.
