Any idea how to make this work?

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
