Right now, when a message is sent during a full redis failure (cluster completely down -- but probably applies to not-enough-slaves only as well), the system does not send a message, but seems to act as though it was sent... get started returns nothing, but then a follow-up returns an invalidation error as thought the opening text was sent.
