Code

function render_example_cache_pre_render($element) {
  $element['#markup'] = render_example_cache_expensive();

  // The following line is due to the bug described in
  // http://DOCUMENTATION_PENDING/node/914792. A #markup element's #pre_render must set
  // #children because it replaces the default #markup pre_render, which is
  // backdrop_pre_render_markup().
  $element['#children'] = $element['#markup'];
  return $element;
