Open Stack

I accidentally didn't reply-all. Forwarding this now for the record.

Apparently this has helped Damian. Perhaps we should cut a minor release of
zuul?

Hey Damian,

So I think https://review.openstack.org/#/c/362049/7 might fix your issue.
Have you tried installing zuul from source to see if that fixes your
problem?

If so, maybe we should do a minor release.

Cheers,
Josh
