That's just how it is. If you want to hide this effect, write a two-line function based on Luigi's code.

I suppose Patrick wants to retrieve the contents of the MVL. This does it:

   local p1 = node.copy_list(tex.lists.page_head)
   local p2 = node.copy_list(tex.lists.contrib_head)
   node.insert_after(p1, node.tail(p1), p2)
   tex.box[0].head = p1
   tex.lists.page_head = nil
   tex.lists.contrib_head = nil

Well, it seems to work, but something tells me it is a very bad idea. 
Not the kind of thing I'd rely on until I've had a better understanding 
of the page_head/contrib_head interaction, at least.
