Re: ptrace improvement: PTRACE_O_INHERIT

That's what it looks like in the code to me as well.  But my recollection
is otherwise.  And IMHO it should be otherwise, that is that MT exec cannot
be arbitrarily delayed by any userland act.  As long as the de_thread delay
is an uninterruptible wait not even affected by SIGKILL, it looks like a
DoS sort of vector if userland can prevent the other threads from dying
quickly.


Thanks,
