Wow it took 10 hours to start, and then 5 hours to run! With just one other build during that time.

It still failed:
https://buildbot.python.org/#/builders/500/builds/2027

And is now failing on other branches so I suspect it's a problem with the buildbot machine. The builds just to run in under an hour.
