The concept is not tricky.  I just can't find the appropriate words.
I *suspect* this can mostly re-use the existing css_set thing.  It
mostly becomes that css_set belongs to the unified hierarchy rather
than each task.  The user interface part isn't trivial and maybe
"don't nest beyond this level" is the only thing reasonable.  Not sure
yet whether that would be enough tho.  Need to think more about it.

Thanks.
