10 messages is not a lot. I would guess (hope!) that 10 messages can be
sent in less than the time it takes to start the second sender
processes. Try 10000 messages before you raise a bug.

--------------------------
In the senders, I am only sending one message per second, so I get to see them
printed out by the receiver as they arrive.
So if credit were distributed across both links, I would expect to see messages
come in randomly from both senders, until they are both done.
