 I'll explain directly with an example of the scenario, for better
 understanding I hope.

 A function registered through add_action('save_post','callme_back');

 with the following code:

 {{{
 function callme_back($postId) {
     static $runmeOnce=true;
    if ($runmeOnce) {
      $runmeOnce = false;
      wp_insert_post(get_post(21431/*whatever, just to trigger save_post
 again*/));
     }
 }
 }}}

 causes the internal array pointer of $wp_filter[ $tag ] to skip all
 the remaining calls to the filters for $postId, as a result of having
 already called all of them for $postId+1 and reached the end of the
 pointer.

 A solution is making a copy of $wp_filter[ $tag ] first.
