Yes. I knew about this ahead of time. I caught patchset 21. Patchset 22 came in while I was out at dinner. Perhaps I need to be more diligent about highlighting these sorts of failures... but as a non-gate SmokeStack is only so scalable. In general I don't mind this sort of thing (I'm used to it), and we can always do a quick revert... until we can't when the patch is like 1500 lines long :(.

I'm happy enough with the turn around here... just wondering if a slight config change to our upstream gating system might help out here. Right now we already spin up two devstack-gate instances for each zul run (one with quantum, one without). Why not take one these and spin it with a Fedora 18 Qpid setup? Seems like a simple change and we'd have this covered without too much issue.
