We fixed the `bind(): Address already in use [core/socket.c line 769]` error in LB using `exit-on-reload = true` in uWSGI configuration. However, this prevents graceful reloading. I did some further investigation as noted in metabrainz/artwork-redirect#46 and have a better fix in mind now. For the command field in exec block of consul template configuration, use array format. This executes the command directly without spawning a shell wrapper or setting a process group id. Both of which will interfere with forwarding signals to the uWSGI process.
