It's initialized with new HibernateList(DetachedCriteria criteria,
Session session, int fetchSize); when you call get(10) it will test if
it has already fetched, if not will fetch from 10 to 10+fetchSize
element. The size() method is implemented moving the cursor to the last
row and returning the index of it. As told we're testing it on a 11000
very heavy object list, and it's working perfectly, we see only 10
selects done to fetch the objects when the get(x) method is first called.

Yep. It will be part of the documentation actually, because we don't
want to introduce a dependency on Hibernate in cocoon itself, anyway
it's apache license so it will be public.
