    // Force to regenerate the stored list of hook implementations.
    module_implements('', FALSE, TRUE);
  }

  foreach ($invoke_modules as $module) {
    module_invoke($module, 'enable');
    // Check if node_access table needs rebuilding.
    // We check for the existence of node_access_needs_rebuild() since
    // at install time, module_enable() could be called while node.module
    // is not enabled yet.
