This addresses the minor issue I brought up in #440.
next_worker_index
will now always be a number between 0 and the number of workers configured.I also added an integration test (t3.rb) that boots multiple workers and utilizes on_worker_boot. Perhaps it's testing too many things at once (multiple workers, on_worker_boot hook, index) — but it felt nice to have that code path tested.
Feel free to pull or just use as inspiration :)
