hmm, very interesting: the cache directory was writable, but for some 
reason the directories wordpress had created inside were not (tried 
deleting them and they were again created without the write permission); 
however, deleting tha wp-content/cache directory and letting wordpress 
create it led to correct permissions;

btw, WP_Object_Cache::make_group_dir seems  to be repeating the work of 
wp_mkdir_p...
