FlowVar.^ blocks even if isReady returns true

[zacharycarter]

Given the following example : https://gist.github.com/zacharycarter/54543ce5ff5dd00b03d4bfb4d81ae663

Retrieving the value of the flow var blocks the main thread for 2+ seconds even though FlowVar.isReady returned true.

Closing this for a couple of reasons -

1. I don't use threadpool anymore
2. I'm not sure if this is still relevant at all
3. Overly complex example code
