[wp-hackers] Resetting after multiple loops

wp_reset_query resets the global $wp_query, but with that code there's
nothing needed to put something back to the original state because the
$wp_query never got changed.

What  "side_effects" are you seeing? The only side effect will be that
the global $post and $id are used, because of the call to
query->the_post(), but nothing else will change. And the $post and $id
and such only affect those the_* functions, which are Loop-Only
functions to begin with.

In other words, a new WP_Query has no real side effects to speak of,
and if you're seeing any, then you're doing something else wrong.
