+ // Note: We use this approach instead of "sudo"

+ // docker container, and our passenger child process
+ // changes to pgid 1) the intermediate sudo process
+ // notices we have the same pgid as our child and
+ // refuses to propagate signals from us to our child,
+ // so we can't signal/shutdown our passenger/rails
+ // apps. "chpst" or "setuidgid" would work, but these
