(The following is not a disagreemtns in any way, but a reinforcement of the
point in an effort to further defend preemptive multitasking, UNIX, and GNO/ME)

But if they do not give up their time, it will be taken away soon enough! For
that reason, I don't think you can get away with defining that as cooperative
multitasking. All of the concepts, systems, etc. of preemptive multitasking
still apply. Although blocking a process is similar to cooperative
multitasking's technique, the concepts of coop are simply not there.
