[Bug 853908] [NEW] urllib.urlopen patch causes reading beyond last byte of https responses to take unreasonably long

[James Aylett]

Public bug reported:

Importing M2Crypto patches `urllib.urlopen` to "better" support https
(possibly a hangover from when urllib didn't support it at all?). The
version in natty does not correctly process the end of the response, and
takes approximately 300 seconds to return.

Example:

import urllib
d = urllib.urlopen("https://www.google.com/").read() # returns almost at once
from M2Crypto import SSL
d = urllib.urlopen("https://www.google.com/").read() # returns about 300 seconds later

These should be equivalent.
