From: Oleg Nesterov <oleg@redhat.com>
Subject: fs/exec.c:de_thread: mt-exec should update ->real_start_time

924b42d5 ("Use boot based time for process start time and boot time in
/proc") updated copy_process/do_task_stat but forgot about de_thread(). 
This breaks "ps axOT" if a sub-thread execs.

Note: I think that task->start_time should die.
