If I understand your scenario correctly: you want to create
consumers/queues/bindings, while blocking waiting for a message using

Unfortunately SimpleAmqpClient and the rabbitmq-c library it wraps are
single threaded, and don't support this use-case well. You have one of two

- Create a new SimpleAmqpClient Channel object for each consumer. (Note
that a SimpleAmqpClient Channel object wraps an entire AMQP connection, and
manages AMQP channels internally, yes this was a poorly named).
- Use the timeout parameter on BasicConsumeMessage, and occasionally poll
for a new consumers and create the consumers/queues/bindings as necessary.
- Depending on how your application is setup there's probably a third way.
