In nearly every app, if the current working directory disappears, the app becomes broken, sometimes subtly. It can be especially broken when preload_app is false (the default). So just shut ourselves down to spare ourselves the wasted CPU cycles on a dead app. As a (hopefully) pleasant side effect, this allows configurations with preload_app==false (the default) to do application code reloads via SIGHUP (in addition to unicorn config reloads).
