If anybody's interested, there is aparently a userspace equivalent
to the kernel patch:

I haven't tried it myself.

I have but I can't get passed the mount option.

You need a kernel with CGROUPS enabled.

Well I installed 2.6.37-rc2-1 which has CGROUPS enabled
and /sys/fs/cgroup but the mount fails:

# mount -t cgroup cgroup /sys/fs/cgroup/cpu -o cpu
mount: mount point /sys/fs/cgroup/cpu does not exist

In fact
# ls /sys/fs/cgroup/

i.e. nothing there.
So "obviously" those instructions make some assumption tha deons't
hold for us. Some initialization perhaps?

I have 2.6.36-18-pae, the mount point exists. I don't remember having
to do anything extra.
