I was first inspired to look into this when I looked at this bug #4004

It looked like an interesting problem. I’m going to describe the process I used to solve it. I had used Poolboy before to make a request pool so I wouldn’t overload the service I was using, so I knew that I at least had a basic enough understanding so I could hopefully implement it.
