    5 That line in WP_User::_init_caps() is somehow causing cache pollution.  wp_cache_get($id, 'users'), as done in get_userdata(), will sometimes return an object with the wp_xxx_capabilities property set ( where xxx is the current blog id).  The value is an empty array.  This confuses get_blogs_of_user(), which sees that the property is set and mistakenly thinks the user belongs to the current blog.  Since the cache clones objects on set and get this is rather unexpected.
