[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.
