 When saving menus, `wp-admin/includes/nav-menu.php` calls
 `wp_update_nav_menu_item()` for every menu item. This function call can
 take 0.1-0.4s, when multiplied by 50 (or more!) menu items, is a less than
 pleasant experience.

 Because of the length of time this takes, it's also quite likely that an
 interrupted connection could cause the menu to be saved in a weird state.
