Yes, that's the concept. It is rather trivial to solve the actual problems, throw enough mutexes at it and you're done. It is far more tricky to do it in a way where you get both readable source code (so people understand what it does and how it does it), simple conceptual models (so people can understand it) etc. And then of course, once we have that we need a transistion plan, and that in itself is a problem because we want to minimize code sweeps, and we have a lot of practically untestable drivers. >Groovy.
