> The backgroundOperationLock in DocumentNodeStore uses the default non-fair
> acquisition order. According to JavaDoc of ReentrantReadWriteLock it is
> possible that a background operation task gets delayed for a long time when
> the system is under load. We should probably consider using the fair mode for
> the backgroundOperationLock to make sure background operation tasks do not
> get delayed excessively.
