Comment:

 > If you use query_posts and filter the returned columns using the
 'posts_fields' filter, the resulting post objects will be cached, and
 could disrupt normal behavior in your theme.

 I've run into this problem too. Patch adds a 'cache_results' option to
 WP_Query.

 I also noticed that update_post_caches() uses an unefficient for loop,
 when a faster foreach could be used.
