BUT WHAT ABOUT [DEV/PROD PARITY](http://www.12factor.net/dev-prod-parity)?!!

Seriously though, I am a bit torn... I'm annoyed by all the spam `up` tells me about worker processes being created/listening/suiciding/etc, but at the same time, I can think of bugs this might surface in development that might otherwise only surface in production. For instance, if I was a noob and decided to store state in the process, the bugs arising from doing so might actually be surfaced on multi-process `up`, but they would almost certainly never get surfaced on single-process `up`.

Anyways, I'm probably overthinking this, I can just add `-n 1` if you want.
