Rather than killing Gunicorn's child processes, I prefer to send SIGHUP to the master process.[1]

It's as simple as

`pkill -f --signal HUP "gunicorn: master \[procname\]"`

The issue with that is that it tends to stop all the workers then start them again, not one-by-one. Since some applications can take a minute to start that leaves the socket open but won't start accepting connections until the workers start again.
