We are using Celery so it just pipes off jobs (and we have some middle layer in place of RabbitMQ that makes it more or less async).
I do plan to add a UDP server, but otherwise this is my recommendation.
One thing I should note, I haven't thoroughly (outside of mock) tested the Raven celery client. I might have fixed a couple of issues in master with it, so if you choose to use it I'd recommend installing master.
