Mount Unix sockets instead of listening on 0.0.0.0 for memcached and postgres?

[jpmckinney]

Unix sockets can easily be mounted as volumes e.g. /var/run/app.sock:/var/run/app.sock

Advantage: Arguably more secure (though external firewall is sufficient)

Disadvantage: Need to figure out correct permissions on the socket itself. Might end up being messier.

Not sure if worthwhile, but thought I'd open an issue to discuss.
