<br>
The priority queuing happens per "gate queue". The integrated gate (nova, cinder, keystone, etc) has one queue, Tripleo has another, OSA has one and so on. We do this so that important work can happen across disparate efforts.<br>
<br>
What this means is if Nova and the rest of the integrated gate has a set of priority changes they should stop approving other changes while they work to merge those priority items. I have suggested that OpenStack needs an "air traffic controller" to help coordinate these efforts particularly around feature freeze time (I suggested it to both the QA team and release team). Any queue could use one if they wanted to.<br>
<br>
All that to say you can do this today, but it requires humans to work together and communicate what their goals are then give the CI system the correct information to act on these changes in the desired manner.<br>
