Code review comment for ~ahasenack/ubuntu/+source/cyrus-sasl2:kinetic-sasl2-digestmd5-noise

Some inline discussion but mostly me talking to myself, nothing that really has to be changed.

I'm not sure how this is enacted in the client, but I noticed you asked that question and got an answer, and you've tested thoroughly enough to confirm it does behave as expected in practice, so presumably you're confident it's being enacted properly.

Everything LGTM, +1.
