[rabbitmq-discuss] AMQP and Python

Just for completeness sake - Qpid is a broker and several client  
implementations, including a python one.

We're using the Qpid python client (actually an old version),  
primarily because it was the only one available at the time we started  
with RabbitMQ.

I have no measurements on performance.

We don't want to use twisted and be forced to code in event-based  
style and py-amqplib doesn't seem to handle multithreaded code too  
well (at least that's my current understanding - please correct me if  
I'm wrong). So there's no real alternative to using the Qpid client in  
my case.
