To be a real time one, you need to do something in predictable time frame. Now, take a time and think for your self, is being "preempt" alone could guarantee it? What if, let's say, you're doing task A, then being preempted by task B, could you guarantee A to be finished in x milisecond? in shorter word, preemption increase responsiveness IMO, but it doesn't make kernel a real time one. And be careful, there's soft real time and hard real time. Linux, in proper patch, could get near to be soft real time OS.....
