Truncate temporary table commits transaction?

Is this correct that a "CREATE TEMPORARY TABLE IF NOT EXISTS.." does not commit current transaction (I like that), but a TRUNCATE TABLE, which is temporary, does implicitly commit any transaction?

Does this mean that the only way to have a fresh temporary table without committing the current transaction is to run (after above DDL statement):

DELETE FROM temp-table-name;

This TRUNCATE auto-commit behavior caused a rather nasty bug in my app -- the rollback didn't go all the way up because of the "TRUNCATE barrier" ;)
