From: Slobodan Blazeski on
After discussion about Persistent Arrays http://bit.ly/b4lZJR I tried
several strategies and decided to go for B+ tree. http://bit.ly/45qCtU
However my arrays (now trees) tend to grow quite large so I want to
manage the B+ tree without keeping all of the nodes in the RAM. Does
anybody has some experience how to organize on demand loading and
releasing the node and is willing to share it I would be grateful.

thanks
Slobodan
