import random
from locust import HttpLocust, TaskSet, between

products = [
    '0PUK6V6EV0',
    '1YMWWN1N4O',
    '2ZYFJ3GM2N',
    '66VCHSJNUP',

def index(l):
    l.client.get("/")

def setCurrency(l):
    currencies = ['EUR', 'USD', 'JPY', 'CAD']
    l.client.post("/setCurrency",
        {'currency_code': random.choice(currencies)})

def browseProduct(l):
    l.client.get("/product/" + random.choice(products))

class UserBehavior(TaskSet):

    def on_start(self):
        index(self)

    tasks = {index: 1,
        setCurrency: 2,
        browseProduct: 10,
        }

class WebsiteUser(HttpLocust):
    task_set = UserBehavior
    wait_time = between(1, 10)

I believe this could be fixed by either downgrading or upgrading the version of gevent (probably downgrading). So you could try that, or even better upgrade to Locust >1.0 (locust package on PyPI) or at least 0.14.6 (locustio package on PyPI).
