------from chris's post----------
I'm running a set of ~50000 queries on one table, using inserts and updates,
and i want to be able to roll them back so i turned off autocommit using
setAutoCommit(false). As the update runs, the memory used by the JVM increases
continually until i get the following exception about 20% of the way through:
ERROR 40XT0: An internal error was identified by RawStore module.
