Subject: [PATCH] [PATCH] avoid tasklist_lock at getrusage for multithreaded
 case too

Avoid taking tasklist_lock for at getrusage for the multithreaded case too.
We don't need to take the tasklist lock for thread traversal of a process
since Oleg's do-__unhash_process-under-siglock.patch and related work.
