Out of curiosity: what makes the new flag different than say
CLONE_NEWCGROUP or any new clone flag that got introduced?
CLONE_NEWCGROUP too would not be detectable apart from the method I gave

to detect this flag when other flags didn't seem to matter that much.

I wasn't following uapi changes closely enough those days. ;)
