If the differences are not in the database, my best guess would be that
you are hitting the ugly synchronization on the DataRowStore since the
problem seem to be with concurrent commits.

It would be very interesting to see the same test with a quickfix on
DataRowStore that removes all of the synchronization and uses stuff from
java.util.concurrent instead.
