So if I fork/exec staprun from a program, then want to kill staprun/stapio from that same program, how can I do it?  I only have staprun's pid.  

BTW, I'm asking this for the SystemTap GUI team.  Before stapio was added, they could start/stop staprun using staprun's pid.  Now that stapio is involved, that doesn't work anymore.

Thanks,
Mike
