Overview:

Google earth query process does not go away after stopping roslaunch. It hangs forever.

screen shot on 2016-08-31 at 14-49-43

Requirements:

make query writer process die as expected when its parent gets killed or shuts down

Development notes Probably look into QueryQueue that uses threading.

Testing scenario

lg-sudo-bg stop roslaunch ssh to 42-a and verify that process does not exist.
