* This is useful for ParserCache, as it tries to focus on memcached and use other caches (e.g. mariadb) for the long-tail of less used content, as setup on WMF. The class uses BagOStuff in a way that is compatible with this approach. Bug: T109751 Change-Id: Ia64eb44a9b52a988fde27b468d604d9163bed4b4
