The magic phrase you're looking for is "process group". When you press
control-Z a signal is sent to all the process in the process group, but
when you send a "kill" it's only sent to one process.
So
% ps -o pgrp $your_process
That'll tell you the process group. Then you kill -STOP -pgrp
(note the negative ID sent to kill)
That'll send a signal to all processes in the group
