while i am fighting for "one image build per launchpad MP landing" since
a few years already, please note that this means rootfs builds ... 

since launchpad switched to shared (package) buildds for rootfs builds
we are depending on having a free builder available in the
infrastructure (multiplied by number of arches we support). 
at times of full archive rebuilds of the distro and other high times
(right before freezes in the distro there are usually tons of uploads)
where the builders are under heavy load your image/rootfs build request
might sit for hours in the queue until a free builder is available (or a
buildd admin forces it through manually) ...

so we should make sure that we dont have actual time critical
expectations in this process atm.
