Had a quick look at your patch set.  No, it does not seem to meet my
requirements.  It limits the number of processes in a cgroup - that is
also very useful, but is different from my controller.

My controller limits the number of fork() calls, not the number of
processes running at a time.

I've been using it for 7 years to put an upper bound on CGI resource
usage in a shared hosting environment at my employer (initially based
on a proprietary cgroup-like subsystem I wrote, when cgroups were not
available yet).
