Optimistic Updates in Flux: The Action Queue

Hey there all. I've been looking around for implementations of an actions queue in Flux but haven't found any. I decided to try to give it a go myself and answered this guy's SO question about it.

Is there a better way of doing this? This seems like the correct approach to me.
