In order to prevent accidental fork bombs we need to add a new docker daemon option to set the default maximum number of processes within a container. This max number should then be set in the cgroups created for each container.
PR for docker here https://github.com/projectatomic/docker/pull/333
The fix for 1.12 isn't merged as I believe there's no path forward to ship a docker 1.12 at all. The PR for 1.12 is still here: https://github.com/projectatomic/docker/pull/334
Assuming this blocker BZ is just for 1.13, this is in POST so we just need to rebuild docker wherever necessary. CC'ing Lokesh. Let me know if we need to merge and ship the 1.12 fix (even if I would strongly discourage shipping such a feature to such an old package).
