[jar349]

it's a change in tornado, it looks like: jupyter/notebook#3397

[zakkg3]

Thanks @jar349

I get the event loop error shown above when I try google oauth with Tornado 5.1.1. Do we really still need to rollback to Tornado 4.5.3 ? I tried that and am getting a 403, however I'll allow that maybe something else is wrong in my config so I'll keep trying with the old tornado.

To follow up, I didn't have the Google+ API enabled when I tried it with Tornado 4.5.3. If Google+ goes away, does that API go away too?
