I believe so, yes, because I store shared_ptr copies of the cached

        /** Get the cache item associated with file.
         * Returns an empty container if there is no such item.
         * IMPORTANT: whatever uses an image must make a local
         * copy of this ItemPtr.
         * The boost::shared_ptr<>::use_count() function is
         * used to ascertain whether or not to remove the item
         * from the cache when remove(file) is called.
         * You have been warned!
        typedef boost::shared_ptr<CacheItem> ItemPtr;
        ItemPtr const item(std::string const & file) const;

The app in question does not use weak_ptr at all (anymore).
