did most of the above, and did get it to work, but mallocing must be consider different storage, it doesn't produce a oom kill.
the RTFM approach was done first, but like a lot of the tools the apis are in flux and knowing what to do is a hair pulling process. the way it did it is doc'ed in the kernel docs.

Did you "man systemd.cgroup"? Do you have to do something to turn memory accounting on to make this work (perhaps i
n/etc/cgrules.conf)? Have you tried setting up a.out as a service with the appropriate MemoryLimit=bytes and/or
MemorySoftLimit=bytes settings set and then tried to run it as a service?
