 I can't understand your question here. Did you notice the parent, 
 /sbin/init? Isn't the job of init to finish zombies? The process isn't 
 actually running, ktrace produces zero lentgh file - but somewhere in 
 kernel (?) it is considered running - why? If it is kblanscrn.kss who 
 sucks, why it doesn't even do NOOP?
