Endless loop with wp_insert_post and wp_update_post

Question

I have an array $unqiues which contains URL's, I loop over the array with the code below to get the URL titles, insert a new post, update the post meta. Then I change the the posts title and name to the $pid which was returned by wp_insert_post.

This created an endless loop, I have about 600 or fewer URL's in the $unique array. I just hit 75,000 queries within an hour on my host and have to wait an hour for the limit to reset. What caused the endless loop? This code worked when I tested with 10 URL's in the array.

How can this be written more efficiently?

Thanks

foreach($uniques as $unique){
      $pagetitle = getTitle($unique);
      $new_post = array(
            'post_title' => $unique,
            'post_status'   => 'publish',
            'post_type' => 'websites'
        );
        $pid = wp_insert_post($new_post);

        update_post_meta($pid,'title', $pagetitle);
        update_post_meta($pid,'url',$unique);


          $my_post = array(
              'ID'           => $pid,
              'post_title' => $pid,
              'post_name' => $pid
          );

          wp_update_post( $my_post );
}
