This does a better job of handling unexpected CID and AMD messages by not relying on the alias algorithm's state machine to send the replies. This removes some race conditions from the reactions.
In the process of debugging this, I found that several of the tests also were timing-dependent. They'd only fail occasionally, but they would occasionally fail. Those tests were actually tests of the underlying negotiation to converge, and sometimes they'd take a different path to convergence depending on the exact timing of the RID and AMD messages. Given that we've established by now that the negotiation does converge, I've disabled these tests.
