Show HN: Que, a Ruby-PostgreSQL job queue with ~20x the throughput of DelayedJob

Hi everyone - I wrote a job queue called Que, which uses Postgres' advisory locks to manage jobs very efficiently. My goal is to make it easy to cover jobs with the same ACID guarantees as the rest of your data. It won't be as fast as a dedicated or Redis-backed queue, but I expect it will be fast enough for many use-cases.

The 20x figure comes from a benchmark I ran on an AWS c3.8xlarge instance - this number will change depending on your hardware. The code for the benchmark (and some more detailed results) is here:

I'm very much open to thoughts and suggestions - please let me know what you think.
