As this subsystem is named "rlimit", I think we should have a bigger
picture about how this subsystem will be.

For example, which of other RLIMIT_XXX can be make cgroup-aware in
a meaningful way and which can't.

Another issue is, we can apply the limit of RLIMIT_NPROC as the sum
of the tasks' limit in a cgroup, but some other RLIMIT_XXX can't
work in this way. Take RLIMIT_NICE for example, we can apply this
limit to each of the tasks in the cgroup.
