For what it's worth, the non-SPL interfaces use ZEND_ABSTRACT_ME or
similar as far as I can tell. Also, reflection says that all of the
interface methods are abstract (which they are, in the sense of not
having any method body).

I think the key issue is that _in the docs_ some interface methods are
marked up as abstract, yet others aren't.  I suggest making them
consistent, having them all being one or t'other.
