You make interfaces, write everything beyond off as a total failure, and worry about containment and the impending rewrite of his part later. Its like managing a burning forest, you cant extinguish it after a certain dimension is reached, you can only cut the fire from the food and keep it from spreading. The problem is, when your colleague is supposed to work on the same module and you are constantly left debugging stupid stuff out of "working code" he wrote. Management scolds you for being "slow" while the moron gets to play the fast car.
