Created May 29, 2015 17:55

Failing issue with geventwebsocket + newrelic instrumentation. run via `chmod +x run.py && ./run.py` and navigate to http://localhost:9191. After the first websocket connection, no more connections are allowed. Commenting out NR instrumentation restores expected behavior.
#!/usr/bin/env python2.7
# pip install newrelic gevent gevent-websocket flask
# my versions: (2.50.0.39) (1.0.2) (0.9.3) (0.10.1)
import newrelic.agent
from geventwebsocket.handler import WebSocketHandler
from gevent.pywsgi import WSGIServer
