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
