No, any attempt to build namespace support into cgroup core code will
be nacked with strong prejudice. I still think it was a mistake to
add that to sysfs. Thankfully, procfs is going the FUSE way and I
hope in time we could convert sysfs to a similar mechanism and
deprecate the in-kernel support.
So, no, no, no, no, no, no, no, no, no, no, no, no. :P
