> TestTxnCommands2#writeBetweenWorkerAndCleaner with minor
> changes (changing delete command to insert command) fails on MM table.
> Specifically the last SELECT commands returns wrong results.
> But this test works fine with full ACID table.
> ======
> MM table inserts were not making entries into TXN_COMPONENTS, thus the
> {{txnHandler.cleanEmptyAbortedTxns();}} logic in {{Initiator}} can wipe out
> TXNS entry for an aborted transaction before the relevant files on disk are
> removed.
