as of systemd 224, mem limits do not work from user acct, so you need to run that one as root

• systemd-run --scope --uid username -p MemoryLimit=100M ./some-app - create cgroup then run app in it. MemoryLimit applies only to memory so for example setting it to 100MB will make app use 100MB of RAM and then swap the rest
