I propose the attached patch as fix to this issue. All it does is, moves the

from urllib.request import urlopen
print(urlopen('https://mtgox.com/').read())

prints b'' rather than the page content.
It looks like mtgox.com always sends 'Connection: Keep-Alive'. So some hack

Could we look for 'tion: Closed' instead of Connection: Closed, to accomodate
