Network stacks are incredibly complicated pieces of software, and some of the short-cuts jail took to accomplish its goals without implementing true virtualization break down when generalized. The patches to date have made the code more complicated and added more edge cases, and we'd like to avoid adding more edge cases to the stack if we can avoid it, as every edge case offers the opportunity for bugs and maintenance issues. The current patches Bjoern is preparing address most of these concerns, and they've been undergoing review and testing for a few months now. I'd like to think they will be in 8.x relatively shortly (next week or two), and in 7.x before 7.2. Robert N M Watson Computer Laboratory University of Cambridge
