So to be clear on this, in that case the intention would be move 3 to 4,
4 to 5 and 5 to 6
to keep the node ordering the same?
Would it make more sense to do 5->6, 4->5, 3->4?  If we move stuff
from 3 to 4 before clearing the old 4 stuff out, it might get crowded?

Yes, I didnt try to imply the order in which pages were moved just
the additional moving necessary.
