I want to go over the code in depth to grok the design more fully. It would definitely help if you (and others) could think about the API being added: Does it fulfill the promises being made? Does it offer the guarantees that real-world apps want to have? I'm not much of an application writer myself -- particularly high-traffic apps that would want to use this. As a driver author I would welcome your insight in these questions.
