Well, you can get true serializability and ACID for all transactions, without question, by using a single-threaded database engine and executing only one transaction at a time. The difficulty comes in getting concurrent access and integrity as well...
(Not saying that InnoDB does this - just pointing out that safety properties are only half of the requirement, you must count performance too.)
