Thinking about this some more, I really don't like having such a large
hole where vm_locked accounting can be wrong.  I would prefer to stick
with the current code, which has at worst a short window where
vm_locked is too high.  I don't like making it possible for a buggy
userspace process to leak vm_locked (even though it is technically the
process's own fault).
