afaict, a consumer cancellation will result in an invocation of 
SharedQueue.Close(), which, according to the docs 
(http://www.rabbitmq.com/releases/rabbitmq-dotnet-client/v2.8.7/rabbitmq-dotnet-client-2.8.7-client-htmldoc/html/type-RabbitMQ.Util.SharedQueue.html#method-M:RabbitMQ.Util.SharedQueue.Close) 
and my reading of the code will cause Dequeue() to throw an 
EndOfStreamException *once the queue is empty*.

In other words, any messages received prior to the cancel/cancel-ok will 
remain the SharedQueue and can be retrieved from it as normal.
