Comment (by vdhamer):

 I have a WordPress menu with 90 nodes (and will ultimately need maybe
 150).
 Saving any menu takes a while, but saving this menu now fails after about
 40 seconds. I get a blank screen and the following PHP error message:
 {{{
 May 28 21:45:38 <hostname> apache2: PHP Fatal error:  Maximum execution
 time of 30 seconds exceeded in <path>/wp-includes/wp-db.php on line 1005
 }}}
 It was indeed due to the PHP execution timeout.

 Solving this is IMO urgent because:
 1. it sometimes occurs for very modest-sized menus
 2. many self-hosted users are not in a position to analyze this far
 3. I suspect these timeout may leave orphaned records in the database:

 {{{
 SELECT `ID` , `post_date` , `post_modified` , `post_parent` ,
 `post_content` , `post_name` , `post_status` , `menu_order`
 FROM `test1_posts`
 WHERE `post_type` = 'nav_menu_item' AND `post_status` = 'draft'
 ORDER BY `test1_posts`.`post_parent` DESC
 }}}
 shows a few orphaned records in my database that were created during the
 timeouts and that have ‘menu_order’=1. I can't manually analyze the entire
 menu structure for 'post_status'='publish' because the menus are large and
 I happen to have multiple menus (argggh) for multiple languages (running
 the WPML plugin).

 I incidentally understand that solving this is non-trivial.
