The swapping of the uarea doesn't really introduce a lot of extra complexity, since all it does is allocate swappable pages, just like the swappable pages in user space. Change that mode stuff out of the uarea are probably a bad idea, since it increases KVA pressure by moving them to wired kernel pages. -- Terry
