That _is_ the problem the above will fix. Don't read
"page_launder()" there: it's more meant to be "this is the old
code that does page_launder() etc.."

Trust me. Try my code. It will work.

Except for the small detail that pages inside the processes
are often not on the active list  ;)

But I agree with your idea that we really should make sure
we have enough pages available to choose from when swapping
stuff out.
