A caveat about using a bundled unicorn binary (via `bundle exec unicorn`): if you use capistrano-based deployment, make sure to use a shared vendor/bundler_gems!
Obviously this is much faster than re-bundling each release, but it also prevents the unicorn binary from going missing -- if unicorn is originally executed as /app/releases/XXY/vendor/bundler_gems/bin/unicorn and that release gets rolled back or pruned by :keep_releases, the original master's binary is now gone & it will no longer be able to fork new unicorn masters (is this expected behavior/a known issue?)
