To heck with systemd, it looks like control groups will do the trick!
- create a control group, details about all the switches unclear but
this seems to at least come close:
sudo cgcreate -t kentborg:kentborg -g cpu:foogroup # Yes, root needs
to do that, but it's one-off (per boot?).
- create my processes in that group:
$ cgexec -g cpu:foogroup watch ls &
[1] 16137
$ cgexec -g cpu:foogroup watch ps &
[2] 16162
- Find them in a pseudo file:
$ cat /sys/fs/cgroup/cpu/foogroup/tasks
16137
16162
- fg and kill one, check again:
$ cat /sys/fs/cgroup/cpu/foogroup/tasks
16137
Cool!
Thanks,

P.S. Less important, but could be useful: Anyone know if Mac OS has
something like this?
