Indeed. On the other hand, maybe we /will/ need the buffer
head again soon?

Linus, I remember you saying some time ago that you would
like to keep the buffer heads on a page around so we'd
have them at the point where we need to swap out again.

Is this still your position or should I make some code to
strip the buffer heads of clean, active pages ?

Rik
