acts_as_service

https://github.com/bmpercy/acts_as_service

A gem with a mixin to let you turn a class into something that runs like a service, which you can MyService.start, MyService.stop, and MyService.restart. It tracks its own pid. For now, pretty sure it requires that the class is running inside a rails context (e.g. run by script/runner MyService.start), but that could probably be changed without too much difficulty.
