What is the intended semantics here? Chris' explicit commitTransaction would
throw an exception if the transaction was aborted due to data inconsistency,
leaving it up to the script to retry --- and making it clear to script
authors that non-storage side effects during the transaction are not undone.
How would you handle transaction aborts?

healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
