This only affects DEPLOYED installations.
This does not take care of removing old versions of static files from
that directory. The problem is that staticfiles is clever and
doesn't copy files that are already there, so we can't depend on
mtime for detecting which files we no longer need. Hopefully that
won't be too much of a problem for now.

Nginx's fastcgi buffers default to 8 pages (32KB). I've bumped it to 4MB,
as queries like get_old_messages take something like 130KB, and was
being ferried off to disk. In case this change to the buffers parameters isn't
enough, we explicitly set the maximum temporary file size to 0; if the fastcgi
request goes over the buffers allocated, the request will be handled synchronously,
and never go out to disk on nginx's fastcgi requests.
The manual step that must be done is to apply changes to /etc/nginx/humbug-include/app
from servers/puppet/modules/humbug/files/nginx/humbug-include/app.
The nginx process can be reloaded with `/etc/init.d/nginx restart`.
This must be done for both staging and prod.

We let supervisor create the socket for us by making humbug-django a
fcig-program. Unfortunately, supevisor doesn't support putting
fcgi-programs in groups (see
https://github.com/Supervisor/supervisor/issues/148), so we have to
restart tornado and django separately.
To deploy, copy the config files over and restart nginx and
supervisor (via stopping and then starting it because restart is
broken). I believe the automated restart as part of
update-deployment will fail because of the way supervisor treats
programs in groups. If so, after restarting supervisor, you will
also need to run restart-server manually to fill the caches and then
delete the lock directory in humbug-deployments.

This requires manual steps on deploy to each of staging and prod:
(1) Run the new update-deployment code to setup the initial deployment directory.
(2) Restart all the programs running in screen sessions.
(3) Deploy the nginx changes and restart nginx.

The new nginx configuration file needs to be copied to
/etc/nginx/humbug-include and nginx needs to be restarted when this
commit is deployed.
