When running o-s-t, and specifically when running add_secondary_storag, lago command is taking 100% CPU. I'm not sure where and why, and trying to narrow down the relevant threads did not yield a lot - it's not the Glance related functions, for example.

I did try to make some changes to testlib.py, in an effort to reduce what I thought was a tight loop, but it made no effect (nevertheless, I think those are good changes):

Any ideas how to debug this? I'm on F26, with latest Lago.
