Define a RsbUndoFilter (or whatever) to filter out records that are in
the undo log for the table in question. VIO's sole job is to get and
put data records on data pages. It shouldn't be involved at this level
at all. There's also no need to clutter other classes with a specific
filter type rsb can handle the problem.
