     "Cooperative" mean subjects of cooperation know about cooperation and
_should_ do some actions to support this. This counted as worsted point in
Win3 design because this is hard to obey when produced many apps by many
vendors - this is why even Win3 native app can so easy to freeze Windows.
But DOS apps designed without cooperation in mind, so preemptiveness for
multitasking DOS apps is required.
