> For RM driven recovery, two consecutive recovery scans are performed with a delay between. Only Xids appearing in both are eligible for recovery. This prevents momentarily prepared, normally executing branches from being incorrectly aborted.
> RecoveryXids.toRecover incorrectly compares the content of the two lists, leading to some Xids not being recovered in a timely manner if the list content or order partially changes between scans.
