Comment (by Tom Braider):

 Maybe some new informations.
 Flush zlib compressed buffer stops site creation at this point. So i don't
 flush it an the update site will show normal.
 Also chr(0) instead of [SPACE] don't work for me to fill the buffer.
 {{{
 function wp_ob_end_flush_all()
 {
     echo "\n<!--".str_repeat(' ', 4100)."-->\n";
     $levels = ob_get_level();
     for ( $i = 0; $i < $levels; $i++ )
     {
         $b = ob_get_status();
         if ( strpos($b['name'], 'zlib') === false )
         {
             @ob_end_flush();
             @ob_flush();
             @flush();
         }
     }
     @ob_start();
 }
 }}}
