Good question.  If the pager is not wired then it needs some support
from an external task which is able to page the pager's code and data.
This task may or may not be wired, however, eventually, somewhere up
the paging hierarchy, something needs to be wired.

The next question would be: what does this mechanism look like?  I
don't yet have a good idea.

Thanks,
Neal
