Unfortunately MySQL only supports transactions on InnoDB, BDB and NDB
Cluster tables, and Typo3 is hard-coded to create all tables as MyISAM.
Therefore with Typo3, it'll silently ignore BEGIN/COMMIT statements, and
auto-commit your statements one by one if you try to start a transaction
with BEGIN.
