I've been avoiding the Linus paging ones because they seem to make my
machines all crash repeatedly under any kind of serious test load. Plus the
fact that after about 3 days they needed rebooting to get back from 386

Rik traced down some more vm races so hopefully ac11 will have some more
progress on this one.
