Hi Paul,
many thanks for finger-pointing towards the kernel.

I am even less knowledgable about this but hope these links help:

1. an overview about CGROUPS from Kernel doc
https://www.kernel.org/doc/Documentation/cgroups/cgroups.txt

2. how Android thinks about them
http://code.google.com/p/cgroupmgr/wiki/cgroupsForAndroid

I have no /dev/cpuctl on the 3.12-master kernel.

3. something about the .config for CGROUPS:

Hope this helps for better understanding,
Nikolaus
