Try adding:
# cset shield --kthread on
It will try to move non bound kernel threads to the system set from the root set.
The results seems to vary from introducing system instability, via doing nothing at all, all the way to actually achieving better isolation, depending on the specific kernel threads you have running and your kernel version. Sometime more then one of the results at the same time. It's really like Russian roulette in a way, only way more geekier...
