Oleg Nesterov 962b564cf1 [PATCH] fix do_wait() vs exec() race 
When non-leader thread does exec, de_thread adds old leader to the init's
->children list in EXIT_ZOMBIE state and drops tasklist_lock.

This means that release_task(leader) in de_thread() is racy vs do_wait()
from init task.

I think de_thread() should set old leader's state to EXIT_DEAD instead.
