What is RabbitMQ for?

[Olivier Mehani]

Hey there,

There is something that I never quite manage to put my finger on.

What is RabbitMQ needed for?

It is mentioned in the deployment guide [0] as an option for production 
servers, but it's not clear what for.

I do run celery separate from paster, and all has been working quite 
well despite the absence of RabbitMQ.

I have, however, had a recuring problem of the uploads sometimes choking 
on a locked (SQLite) DB when I upload a few files in a row. I am now 
wondering if RabbitMQ would actually make this issue disappear by, 
perhaps, serialising the requests so they get processed once at a time?
