I agree about opening up the discussion in another forum like koha-devel, IRC,
or Marseille. 

I'm intrigued by the use of ZeroMQ. How do you see that working, Tomás? When I
first started thinking about background processing, I thought using a message
queue would be a good idea. Since then, I've used an embedded ActiveMQ with the
Fedora repository a bit, but that publishes notifications about record changes.
Celery uses a message queue for sending out tasks and then it can use a backend
like Redis for storing task results. 

I think if we use a database for a job queue, that would replace the message
queue? Or are you meaning using a message queue for notifying other services
like an indexer that there are imported records to index?
