In the real program, the consumer pulls a message off that queue and
adds a bunch of messages to other queues, in a transaction.  I wasn't
getting all the messages I thought I was sending, and I didn't know
why, so I started ripping all the functionality out of both programs
until I had a minimal test case.  I guess it wasn't entirely minimal
because the test case does have that pointless transaction, but it was
small enough for me to post at that point.

Both the producer and consumer sources are in the original message.

I am using mandatory; immediate isn't desired in my case.  My original
question was actually along the lines of how does py-amqplib indicate
to the caller the broker's inability to deliver a message.  Perhaps it
does just raise an exception or something similar; I've apparently
never actually triggered that case.
