      The ReplIndexPrefetch Server Parameter in /src/mongo/db/prefetch.cpp is not thread-safe because it calls into methods in BackgroundSync that are not threads-safe.

      BackgroundSync class snippet:

          void setIndexPrefetchConfig(const IndexPrefetchConfig cfg) {
        _indexPrefetchConfig = cfg;
    }

    IndexPrefetchConfig getIndexPrefetchConfig() {
        return _indexPrefetchConfig;
    }
