Depending on the type of system, they may or may not be under the
control of the programmer. In an embedded environment, the programmer is
the administrator and generally has control over how the groups are set
up. On a more generic time-sharing system it's likely that the
individual programmer won't have control over the groups.

Something I haven't tried is whether or not it's possible to set
ownership/permissions on subtrees within the cgroup hierarchy to allow
unprivileged users/groups to control their own tasks (basically letting
them prioritize their own jobs without being able to affect anything
else). Does anyone know if this sort of thing is possible?
