We weren't exactly standing still post-44Lite and in some areas we've diverged, requiring a careful examination of what would constitute a step forward with the Lite2 code and what would be a step backward. :) Not to denigrate the Lite maintainers, but we've made quite a few changes to the VM system that make it more robust in the face of pathological process behavior (try writing a program that allocates all the memory it can and touches a byte out of every page, then have it fork. With a stock MachVM system, Death! :-). -- Jordan
