> Attachments: drainable.py
>
>
> A sender is opened for an address on which there is a receiver. It sends one
> messages which is accepted. The receiver then detaches and the sender tries
> to send another message. This second message is released and the router
> attempts to drain the senders credit.
> The sender responds to the drain request by not sending any further messages
> but incrementing the delivery_count by the appropriate amount.
> If a receiver attaches on the address again after this point, the router
> issues credit back to the sender, but only issues link-credit=1.
