Right, I think the solution would be to do something like I did here: when dealing with a single instance, query space to get the any instance recorders for the class (and all superclasses) and notify them of the received message.

That'll probably work....but it's uggggggg.  I really don't want to slow down the use of rspec-mocks for individual instances in order to make `any_instance` work.  I'd prefer to keep it how it is (it's how it's always worked, I think) or drop any instance message expectation support entirely (I think stubs make way more sense).
