                Toy WSGI app for testing Open Telemetry `BatchSpanProcessor`
              
          
    Demo wsgi app

This is a toy WSGI app under Gunicorn and uWSGI, used to explore forking behaviours interacting with Open Telemetry (and BatchSpanProcessor in particular).
gunicorn wsgi:app --workers 3
Optionally plus --preload, so that gunicorn will import Python into the main process before forking the workers.
