# ps auxww | grep unicorn # confirm that new master process launched successfully
# ls pids                 # check pid files (should have unicorn.pid and unicorn.pid.oldbin)
# kill -s WINCH 18003     # gracefully stop workers, keeping master process running
# ps auxww | grep unicorn # we also test in browser that app is running correctly
# kill -s QUIT 18003      # gracefully shut down
# ps auxww | grep unicorn # one more check
