Yes, it's an example of what I was mentioning before, that the current modified
implementation of `_bt_readpage`  wouldn't work well in case of going between
pages. So far it seems that the only problem we can have is when previous and
next items located on a different pages. I've checked how this issue can be
avoided, I hope I will post a new version relatively soon.
