Yeah, cool, I think you're right that we'll just serialize the
calls. It may not be worth the complexity, but if we make the OaaS
server able to do a few things in parallel, then we'll re-gain a little
more perf because we'll go back to overlapping the *server* side of
things. Creating flavors, volume types, networks and uploading the image
to glance are all things that should be doable in parallel in the server

465s for a devstack is awesome. Think of all the developer time in
$local_fiat_currency we could have saved if we did this four years
ago...  :)
