A background processing queue - that lets you send stuff off into the background to get done while you don't have to think about (or babysit) it.
The Queue is a simple yet powerful thing, on the face of it - you can queue content to be published. underneath you can add anything you can imagine to the queue and have code fire as things reach the top.
Quickly send content to the queue to be published in the backgoround
Write your own custom queue actions, fire things into the queue and get your custom code to run when they reach the top.
