Minor - We've observed concurrent builds of https://qa.nuxeo.org/jenkins/view/Drive/job/Drive/job/FT-drive/job/master/, because of successive commits in a short period of time.
Note that we could also use the Quiet time setting to group commits.
- We also want a global timeout to prevent builds running forever. Typically, when the job is launched on master and another branch, one of them gets stuck waiting for the OS X slave which is currently a bottleneck.
