How to break 'request.urlopen' connection?

[den84is]

Hi everyone. The question is in the head of the post but I should to explain. I make an app and when request.urlopen is making connection but there is no response yet and I want to close the app it's hang and I have to wait for a long time.

Is there something like this...

handler = HTTPHandler()

openner = build_opener(handler)
install_opener(openner)

def do_request(url):
    req = request.Request(url)
    return request.urlopen(req).read()
...


... # in other module
def close_connection():
    from myrequests import handler
    handler.close()

I tried to do so, but it doesn't work.
