 Replying to [comment:18 ryan]:
 > Or have the plugin call set_found_posts() itself. There's only so much
 that can be done to retain back compat with a plugin that does such deep
 voodoo.

 Or we can type-check it. So, return if `$this->posts === array()` (or
 `is_array( $this->posts ) && ! $this->posts`). That allows a null/false
 for $this->posts to be considered as "hey, someone is doing some crazy
 stuff here, let's not make too many assumptions."
