Could the phrase starting with "It is implementation-dependent..." possibly be reworded to more directly reflect common implementations and the caveat this brings?
Something like:
":meth:__del__ is generally only called once for a resurrected object (though this is implementation-dependent), so it may only be possible to resurrect an instance once using :meth:__del__."
