> Without this there is a race between new and reused containers for task assignments. It is not correct to assign a task to a rack-local new container if there is a rack-local reused container that can also be matched. Unifying the assignment logic can help prevent this systematically. 
> This also sets us up to trade-off rack-local reused container vs node-local new container if we want to do that.
