Yes. This is obviously a concern, but hopefully the background swapper is
never _too_ aggressive, ie it shouldn't be aggressive enough for this to
be a real issue.
The parameters may need more tweaking, and there may be some other minor
changes in the air, but on the whole the basics should be there now.
