I should probably have mentioned, that if all the transactions were
SERIALIZABLE and the report of transactions from the batch was run
as SERIALIZABLE READ ONLY DEFERRABLE, the start of the report would
block until it was certain that it had a snapshot which could not
lead to an anomaly, so the BEGIN for T3 would wait until the COMMIT
of T1, get a new snapshot which it would determine to be safe, and
proceed. This would allow that last receipt to land in batch 3 and
show up on accounting's receipt list with no rollbacks *or*
anomalies.
