Not sure, that would be nice.
It would have to look at its own maps and figure out that two pages mapped
at the top of memory are the stub pages of the outer UML. That seems a bit
ad-hoc to me.
Although maybe we could just say that any two pages there (as long as they
are not stack) cause the stub pages to be relocated simply to avoid a
collision. Here, we're not explicitly looking for an outer UML, just pages
that we are about to stomp on.
