i think you're assuming a few things 1. the amount of memory consumed by linux doesn't matter. 2. the amount of processor consumed by linux doesn't matter. 3. magic isn't built into shared libraries. for example, how do you know that the interface to the screen isn't built into the qt library (or whatever their cannonical graphics interface is)?
