This does not, as I think you believe, test to see if an
object of the class SuperSocket responds to the -close
message. In
fact, it tests to see if the class object for SuperSocket
responds to the +close message.
That isn't correct. The +instancesRespondToSelector: method
tells whether *instances* of a class respond to a selector. To
test whether the class object responds to a given selector,
you'd use [SuperSocket respondsToSelector:].
My bad, you're absolutely correct. I just misread it as respondsToSelector:.
