Cool Ruby gem from the team at Stripe which makes it easy to run multiple copies of a single long-lived process. From their announcement post: Einhorn makes it easy to have multiple instances of an application server listen on the same port. You can also seamlessly restart your workers without dropping any requests. Einhorn requires minimal application-level support, making it easy to use with an existing project. I'm going to take a seriously look at Einhorn before deploying my next app. (also this)
