 I see intermittent failures with the meta tests like the below:

 {{{

 It appears to be an ordering issue.  The arrays contain the same elements,
 but in a different order.  The arrays are a result of `WP_Query` call with
 no `order` parameter.  MySQL does not seem to be ordering the results
 consistently.

 I propose a comparison using `array_diff()` to ensure the arrays contain
 the same elements, but ignoring the order.
