Shotgun: A Rackup that restarts apps on every request
Ryan Tomayko has released Shotgun, a “forking implementation of Rackup.” Its primary use is for reloading apps on every request to make life easier in development (particularly if your Rack-based app doesn’t do reloading itself).

Cool, altho Rack::Reloader (which comes with Rack) works fine for me. The only time I need to restart the server is when I make a change to the config.ru (which I don’t often make changes to).
use Rack::Reloader if ENV['RACK_ENV'] == 'development'… that said, whilst working on a series of screencasts on Rack, i’ve become increasingly frustrated as Thin/Mongrel don’t always like to quit properly via IRB and Rack::Reloader doesn’t work for reloading the config.ru, itself.
If you’re doing lots of development in a config.ru (which isn’t very typical, imho), then shotgun is really, really convenient!
Thanks for this great, super simple tool, Ryan Tomayko!
