> Autopurge retains all log files whose zxid are >= the zxid of the oldest log file that it is going to retain (in PurgeTxnLog retainNRecentSnapshots()). Given that loading the database from snapshots/logs will start with the log file _prior_ to the snapshot's zxid, autopurge should retain this log file as well unless it verifies that it contains no zxids beyond what the snapshot contains.
