Even within an manually administered transaction the setting of
"setQueryTimeout()" will (should?) act on the individual statements that
make up the transaction. If any individual statement within the transaction
exceeds the limit that statement will fail and thus put the transaction into
a "failed" state where a rollback (possibly to savepoint) is required. The
transaction itself does not constitute a statement and as such it can run
indefinitely long regardless of the presence of a statement timeout.
