 Replying to [comment:72 nacin]:
 > I'm open to suggestions on how to better order the various conditions in
 the loop to ensure that common and fast cases are treated higher up.

 I've performed a quick test by iterating each condition 10,000,000 times,
 and the average results were:

 6,479s for `( 0 !== strpos( $key, $wpdb->base_prefix ) )`[[BR]]
 6,123s for `( 'capabilities' !== substr( $key, -12 ) )`[[BR]]
 4,408s for `( $key === $wpdb->base_prefix . 'capabilities' )`

 Looks like we can move them bottom-up.
