[issue21378] ImportError: No module named 'concurrent.futures'

Thank you for your response. The program works as expected.

I removed PYTHONPATH settings for 3.4 and 2.7. I'm not sure how those settings were written. I suspect something related to virtualenv, and I will be watching to see if they are written again.

When I removed those paths, an error message pointed me to a local version of concurrent.py from tornado that was shadowing the concurrent.py in the python3.4 site-packages.
