After all that, Apache::DBI will issue a rollback on the database
handle IF you initiated the handle with AutoCommit turned off.

For people who don't use Apache::DBI or who start their connections
with AutoCommit on and turn it off for brief sections, I recommend
installing your own cleanup handler that will issue a rollback in case
there's an uncaught exception in your code during a transaction.
