That link [1] is for a Git repo. The Mercurial repo [2] where I found the example originally has the broken code without my fixes. Victor Stinner, who owns that repo, refused my pull request saying that he'd prefer not to commit to maintaining the asyncio-tkinter adapter by Dino Viehland. I understand his position, since Dino's code is really a proof-of-concept.

This is working for me on OSX 10.9 with both Python 3.4 and Python 3.5 using the tkinter and the asyncio packages from the Python the respective standard libraries. I hand-tested it again just now (sorry, there are no automated tests for this toy example + POC).
