Comment (by billerickson):

 Regardless of what method you use to generate the loop, if you set the
 post data to something else you'll need to reset it. Using get_posts:


 {{{
 $original_post = $post;
 $myposts = get_posts( $args );
 foreach( $myposts as $post ) :  setup_postdata($post);
 ...
 endforeach:
 setup_postdata( $original_post);
 }}}


 Using WP_Query (how I'm doing it):


 {{{
 $original_post = $post;
 $loop = new WP_Query( $args );
 while( $loop->have_posts() ): $loop->the_post();
 ...
 endwhile;
 setup_postdata( $original_post );
 }}}

 I think it's reasonable to assume that most of the time you're doing a
 query in a metabox, you'll need access to the post data.
