12** Steps to run this test on ubuntu:
13** 1. sudo apt-get install cgroup-bin
14** 2. sudo vi /etc/default/grub
15** Add cgroup_enable=memory swapaccount=1 to GRUB_CMDLINE_LINUX_DEFAULT
16** 3. sudo update-grub
17** 4. reboot
18** 5. sudo cgcreate -g cpu,memory:/myGroup -a <username>:<username> -t <username>:<username>
19** 6. echo 4M > /sys/fs/cgroup/memory/mygroup/memory.limit_in_bytes
20** 7. echo 4M > /sys/fs/cgroup/memory/mygroup/memory.memsw.limit_in_bytes
21** 8. cgexe -g memory:/mygroup --sticky <application>
