     We've been through this.  Too many times.

(2005: Broken in Python 2.2, eventually fixed)

(2008: Why this matters)

(2010: Broken in new Python 2.6 SSL module.)

(2010: Developer "Bill Jansen" in denial, others disagree.
Currently being debated.  See bug tracker.)

The really stupid thing about the current SSL module is that it
accepts a file of root certificates as a parameter, but ignores it.
So it creates the illusion of security without providing it.
As someone pointed out, the current SSL module "lets you talk
encrypted to your attacker".
