Perhaps... but at first glance I think we should not change this
at all.
We are not going to change PTRACE_ATTACH, we can't. We are going
to add the new request which avoids tkill(SIGSTOP). The same with
PTRACE_O_TRACECLONE/etc imho. We need the better control on
auto-attach, but this needs another discussion.
