      Thread deadlock

      Two threads will be stuck waiting forever if each holds a lock the other needs to acquire. Threads may try to acquire two locks in different orders, potentially causing deadlock
      /src/mongo/db/storage/wiredtiger/wiredtiger_kv_engine.cpp:1378: ORDER_REVERSAL 150863 Calling "lock_guard" acquires lock "mongo::WiredTigerKVEngine._oplogPinnedByBackupMutex" while holding lock "mongo::WiredTigerBackup.wtBackupDupCursorMutex" (count: 1 / 2).
