Hmm, interesting. And which one is pointed by td_kstack there? Or they 
are using same segment but from opposite sides?

Why? If variable stack growing down and it's segment is pointed by 
td_kstack then where is the problem? Or you mean that system will die 
earlier when those two stacks in same segment will reach each other?
