If the Transaction Coordinator aborted a transaction in the “prepared” state, this could cause a resource leak. (Bug #14208924)

Now in such cases these files are removed.
In some circumstances, transactions could be lost during an online upgrade. (Bug #13834481)

length specified); previouslyu in such cases, -1 was
returned. In addition, the extra transaction object associated
with the scan is freed, by returning it to the transaction
coordinator's idle list.
