As others have pointed out, pika may be an option. HOWEVER, since the 
2.0.0 release rabbit is using tcp backpressure to throttle producers, 
which should work with *any* client regardless of whether they support 
channel.flow. See the docs at http://www.rabbitmq.com/extensions.html#memsup

What version of rabbitmq are you running? And exactly what problem are 
you seeing?
