title: Get worker id from Gunicorn worker itself
body: <p>I run multiple gunicorn workers with <code>workers=4</code> setting. So as I understand I have 5 different processes: one gunicorn master process and 4 other worker processes. Can I get information about which worker is serving request at the moment? So can I get any worker id from inside worker itself like for each request send back a response with content: <strong>this request was served by worker:worker_id</strong>?</p>
