seccomp vs ptrace

[Serge E. Hallyn]

Hi,

I'm writing to ask about

        The seccomp check will not be run again after the tracer is
        notified.  (This means that seccomp-based sandboxes MUST NOT
        allow use of ptrace, even of other sandboxed processes, without
        extreme care; ptracers can use this mechanism to escape.)

This basically means that seccomp cannot be safely used with for instance
an upstart based container.  I've been told that Andy was working on
changing the order so that ptrace checks would be done before seccomp.
Is there any update on that?  Is it likely to happen?  Scrapped?

thanks,
-serge
