    Øyvind Harboe updated CAY-1075:
    -------------------------------

        Attachment: LinearList.java

    I'm thinking that it is better to leave paged queries as-is and introduce a new class such as the attached one.

    These lists can be optimized for some application specific access pattern.

    Instead of:

    context.performQuery(query);

    the user would use:

    new LinearList(ctxt, query);

    Thoughts?
