Requirements:

• Be restartable without denying or prematurely closing requests (unicorn's SIGUSR2 being the "gold standard")
• Log information about requests in logstash compatiable JSON, including request path, request time & status code. Optionally should include request parameters, content length, content type & time spent in DB, views, external services
• Report exceptions to Rollbar & not die if an exception is encountered
• Connect to external resources via environment variables, optionally also via command line flags (cf 12factor app)
• Allow for automatic destruction/creation of database tables in tests
• Allow for programmatic migration of database tables in production (standard: rake db:migrate)
• Require no filesystem resources other than its own binary (eg, no db.yml or migrations directory)
