I need all of the connections to see the same view of data. With "ordinary" transactions, it is possible for the 5th+ of 10 transactions to see changes which were committed by a transaction that was started before the 1st transaction was started -- ie. an inconsistent view of data. Only if all 10 transactions are started "at the same moment" can consistency be guaranteed.
