使用RabbitMQ构建gearman类型应用程序

I'm looking for a general overview of best practice to implement a "job allocation" system like Gearman using RabbitMQ messaging system.

So basically I'd have something reading the queue and forking? instances to run a job?

Any insight is appreciated.

I would recommend taking a look at Celery which does something like this. Google for Celery and RabbitMQ to get some links, or start here.
