    Andrus,

    I've almost finished the collecting of values from the various BatchQueries.
    The one that remains is getting the old value for a column from
    UpdateBatchQuery. I know that these values are available as part of
    the qualifier when optimistic locking is used, but I don't know if
    that's the best way to get them.

    What do you think of having the old value snapshot stored directly on
    UpdateBatchQuery and made publically accessible? I'm not sure if
    this might make dealing with optimistic locking easier or not in the
    process.
