> The Conditional RW test has roughly two phases.  First it inserts a lot of "banks" where each bank is a row.  The columns in the row represent account balances.  After insertion of all banks is complete, then it starts transferring money within a bank.  If a mutation is silently lost in the insert phase, the test can detect this.  If a mutation is silently lost in the transfer phase, then the test can not always detect this.  The test spends most of its time transferring, so it would be good to modify the test to better detect data loss there.
