      _lastSyncMutex is one of the most contended mutexes when running with {j: true}. This optimization reduces the contention on _lastSyncMutex and avoid serializing {j: true} writer for journal waiting. This also reduces sync-related I/O rate when there are lots of {j: true} writer but will also avoid significant delay in journal waiting.
