I am hoping to be able to stop all of the threads at the beginning of exec so we can write the exec code as if it is single threaded. That is hard but cleanups to enable that change are easy. There is a variable tsk->signal->group_exit_task that is only truly used in de_thread. The changes clean up the coredump code and rename the variable to make it clear that exec is it's only user.
