We should ask Andrew.

But personally I'd like to see them in 2.6.35. These changes allows
us to do more cleanups/improvements.

As for sizeof(int) added to signal_struct. I still hope we can kill
this "int nr_threads" later. Even if not, with these changes we can
move, say, ->group_leader from task_struct to signal_struct and kill
signal->leader_pid.

Oleg.
