>In practice, this is a terrible idea Perhaps it was in the 1980s, but back then applications didn't get funded by downloading adds from third parties using 100% of our CPU. We didn't use many applications at the same time either. So the problem we have right now simply didn't exist back then. And where it did exist, like on mainframes, they did actually use quota systems rather successfully I believe (just as we are right now with virtual machines).
