a simple asynchronous queue
npm install then-queue
var Queue = require('then-queue');
var q = new Queue();
A fresh queue!
Push an item onto the queue
Pop an item from the queue
Amount of items in the queue (note that this can be negative if pop
has been called more times than push

The length-changed

or push
has been called. You could use it to spawn/kill workers when the length changes.
