The process is created in the same cgroup as the parent process, which is the cgroup the Mesos slave creates for the executor and configures according to the executor's resource limits.
Permissions are set so processes cannot be moved up the cgroup hierarchy (which would bypass the executor resource limits) but it is possible for the executor (or other process) to create additional cgroups and thereby change how its resources are subdivided.
