Try installing xdotool, then:

#!/bin/bash
# --any and --name present only as a work-around, see: https://github.com/jordansissel/xdotool/issues/14
ids=$(xdotool search --any --pid "$1" --name "dummy")

I do get a lot of ids. I use this to set a terminal window as urgent when it is done with a long command, with the program seturgent. I just loop through all the ids I get from xdotool and run seturgent on them.
