  $caller = array();
  foreach ($bt as $key => $call) {
    if (!empty($call['class']) && $call['class'] == 'APDQCache') {
      continue;
    }
    if (empty($call['function']) || $call['function'] == 'cache_clear_all') {
      continue;
    }

    // Get this and the next 2 levels from the backtrace.
    $caller[$key] = $call;
    if (isset($bt[$key + 1])) {
      $caller[$key + 1] = $bt[$key + 1];
      if (isset($bt[$key + 2])) {
        $caller[$key + 2] = $bt[$key + 2];
      }
    }
    break;
