 So at this point, we just need a core members decision whether we want to
 tackle this by making it a requirement for cache implementations to also
 key by blog_id and lose the wp_cache_reset() and wp_cache_init() calls
 after the initial load OR if we just call a wp_cache_reset() method if it
 exists when the blog_id changes.
