Connection request hangs without timing out

[levinzz]

Expected Behavior

Connection request always succeeding or timing out

DEBUG __call__(117) Making request: POST https://oauth2.googleapis.com/token
DEBUG _new_conn(959) Starting new HTTPS connection (1): oauth2.googleapis.com:443
DEBUG _make_request(437) https://oauth2.googleapis.com:443 "POST /token HTTP/1.1" 200 None

Actual Behavior

Connection requests work fine for a while, then after a few hours a request freezes and the program hangs

DEBUG __call__(117) Making request: POST https://oauth2.googleapis.com/token
DEBUG _new_conn(959) Starting new HTTPS connection (1): oauth2.googleapis.com:443
--> Program hangs indefinitely

Steps to Reproduce the Problem

1. quickstart.py
2. Make a small change to schedule event requests :

def main():
    while True:
        events = getEvents()
        #do stuff with events
        time.sleep(600)

def getEvents():
    #quickstart code pretty much as is
    #instead of printing, it returns the events

• python 3.5.3
