Some processes are getting orphaned when running Foreman with JRuby.
Creating a new pgroup allows them all to be killed together.
I believe the issue is related to how JRuby handles `Dir.chdir` by
creating a shell process: `sh -c 'cd /chdir/target; ${command}'`. That
causes a second process to be created that won't get cleaned up by
killing the parent.

This sends the signal to all processes in the group. I still saw leftover processes when the signal was sent only to the parent
