A page_by_page_iterator should have an idee of the amount of records it is

some more data in close perimeter to where in the index the user is
navigating ...
-get metadata
-fetch some data to list
- display the list
-prefetch some more
-wait for new input
Also a centralised cache for all users of the iterator -that can act
according to how static the data is ... would help ...
A page_by_page_iterator for really large datasets would work best in tandem
with a lighter db that has a prebuilt index ! ...
