It could do it. Instead of swapping out pages, it should swap
out a page to another (small fragment) place of memory, in the
hope of freeing up large free chunks :-)
But when Ben and Stephen are finished with their plans, I don't
think we'll need to do that...
(if, OTOH, their changes don't make it into 2.2, I'll code up
the inefficient change I just proposed :-( )
