Oh I see your point on being a proper fit. It's not much of an argument then, since you're just saying that making it work when it wasn't quite designed for that use is hard, but we did make it work. So I agree :-) I also wish there weren't any UD, but we did try to do a good list and I think we chose which to fix and which to punt on purpose. I see memory allocation (both for code and data) as well-defined randomness: saying that the allocated base addresses are random allows many interesting types of sandboxing to be used which couldn't be used otherwise (more on that in the future). I think this will lead to interesting perf gain in some cases, and interesting security gains in others. More pragmatically it currently allows ASLR while still providing memory access without indirection (i.e. reg-reg addressing) on x86-32 and ARM.
