 If __autoload is defined, the upgrade process fails with a WP_User_Search
 class not found error.  This is because wp-admin/includes/user.php does:

 {{{
 if ( !class_exists('WP_User_Search') ) :
 class WP_User_Search {
         var $results;
         // ...
 }}}

 If WP_User_Search doesn't exist and __autoload is defined __autoload is
 invoked to define the class, which fails.  The fix is to include an
 optional second argument to class_exists:

 {{{
 if ( !class_exists('WP_User_Search', false) ) :
 class WP_User_Search {
         var $results;
         // ...
 }}}

 (A patch is attached.)
