Sort of...  I have a stored procedure that gets called and updates either 50
or 75 records in a table. The parent table has an inherited table (history)
derived from it with an update rule on the parent table that inserts a copy
of the unchanged record (prior to the update) into the history table. So --
for every 50 updates -- I expect to see 50 inserts into the child.
