Bump! If you run Mesos on a platform that doesn't support O_CLOEXEC (eg. Linux kernel <= 2.6.23), please let us know!

I couldn't find a clear statement of what OS support we guarantee. OS X got O_CLOEXEC in 10.10. CentOS 6.9 has kernel 2.6.32, apparently Ubuntu 14.04 has 3.19. Do we support anything older than that?

Is this altering the minimum Linux or OS X version we support?
