Drupal 6 - Drush warning about orphaned actions

When I was executing drush commands, I got a warning similar to this:

WD actions: 2 orphaned actions (comment_unpublish_action, comment_publish_action) exist in the actions table. Remove orphaned actions

Solution is to use a badly-documented Drupal feature which automatically removes all orphaned actions. Simply visit the following hidden URL on your drupal site: yoursite.com/admin/settings/actions/orphan, and it will remove any orphaned actions and forward you to the Manage Actions page, where you will see they are no longer listed!
