We have multiple teams working on multiple projects. Sometimes everyone else will be waiting behind 5 or 6 builds of one team, especially if that project’s test suite is slow. Obviously the answer is more containers, right!? 
It would be great to have the option of container time fairness across projects. Each project would have its own queue and then available containers would pull from all an organization’s project queues in round-robin fashion.
Or better yet, change the pricing model to give you unlimited burstability and charge based on container run time!
