"""
This is a simple Redis-based queue. Two features that I needed were
uniqueness (i.e. if an item exists in the queue already, it won't be
added again) and a delay like beanstalkd where an item must wait a
specified time before it can be popped from the queue. There are a
number of other Redis-based queues that have many more features but
I didn't see one that had these two features together. This 50-line
class works for my needs. It may or may not work for you. Feel free
to copy this and build on it.
