Can I always use ref_transaction_rollback instead of ref_transaction_free? It would be convenient if my cleanup code could always call _rollback instead of having to do something different for success and errors.

Another way to ask the question: what is it valid to do with a transaction after commiting?

Thanks, Jonathan
