I doubt it. All Node.js libraries are built around the non-blocking model which is why it works so well. Python libraries will have to decide if they're a normal blocking library or an async one. Possibly maintain both versions of the API?

Personally I'm not convinced that the Node.js callback hell is a good way to get high IO performance. The Golang way of doing it with normal, blocking libraries and Goroutine's seems ideal as it doesn't burden the programmer as much.
