http entrypoint does not work with eventlet master

See original GitHub issue

I don’t know whether this bug is in nameko or in eventlet, if necessary I will close this and report upstream

using a very basic nameko HTTP service:

from nameko.web.handlers import http


class SimpleRestServer:

    name = "simple_rest_server"

    @http('GET', '/')
    def get_hello_world(self, request):
        return "Hello, World"

On calling nameko run hello_world.py the service starts normally. With the latest eventlet release (0.21.0), I can then go to ‘http://localhost:8000’ and see “Hello, World”. With eventlet master, when I try to browse to ‘http://localhost:8000’, the nameko service crashes:

$ nameko run hello_world
