Comment (by westonruter):

 In [attachment:wordpress-importer.php.diff], a new
 `wp_import_existing_post` filter is introduced which allows plugins to
 override what post that `post_exists()` detects as being already imported
 for a given post. This also allows plugins to force a post to be imported.
 Additionally, it makes sure that the post ID mapping for such existing
 posts gets added to `processed_posts` for other posts to refer to during
 subsequent imports.
