Comment (by henry.wright):

 Sure @davidbaumwald

 If a website user requests a post by visiting the post permalink and the
 post doesn't exist in our WordPress install, we send a request to an
 internal system to see if data is available to import. If data is
 available the internal system responds with the data and
 `wp_insert_post()` is called immediately after checking again if the post
 exists

 The duplicate issue happens when we are under heavy load and
 `wp_insert_post()` is called with the same arguments in a short space of
 time
