I can't remember if it was with Travis or Jenkins now, but there was a race where it was schedule the job, but before the git repo was checked out someone would push another series. The shallow clone would thus get the commit of the newly pushed series, and would not have enough history to get to the commit that actually needed testing. I guess we could get a win even if we set the clone depth to something fairly large like 100 commits of history.
