Comment (by johnjamesjacoby):

 The only difference between 'array_intersect_key' and
 'array_intersect_assoc' is when an array item is not 'key => value' but is
 instead only 'value'.

 What's in core now:
 http://www.php.net/manual/en/function.array-intersect-key.php

 What's proposed:
 http://www.php.net/manual/en/function.array-intersect-assoc.php

 Another possible alternative is array_intersect:
 http://www.php.net/manual/en/function.array-intersect.php

 Array intersect seems like it could work too, since the _actions should
 match exactly if the intent is to potentially remove them.
