Yes, if you use transactions, i.e. ever turn off AutoCommit.

You can make the CleanupHandler check if AutoCommit is on or not
before attempting to roll back. If you normally have it on, you might
check if it's off, do a rollback if it is, and then turn it back on.
This protects you from an uncaught error inside a transactional block
leaving your database handle in a bad state.
