We have a *ton* of stuff in devstack that is very linear, specifically the ten-ish minutes we spend loading osc to run a single API command against something. We also generate configs, sync databases, and other things that use one core of our worker and make our runtime longer than it really needs to be. The idea in this patch is to make it super simple to run some things in the background and then wait for them to finish before proceeding to something that will require them to be done. This avoids the interleaving you would expect by redirecting the async tasks to a log file, and then cat'ing that log file synchronously during the wait operation. The per-task log file remains so it's easier to examine it in isolation. Multiple people have reported between 22-30% improvement in the time it takes to stack with this. More can be done, but what is here already makes a significant difference. Change-Id: I270a910b531641b023c13f75dfedca057a1f1031
