Comment 35 for bug 907675

The Windows failures were an unrelated problem (https://twistedmatrix.com/trac/ticket/9760), now fixed or at least worked around.

We *could* use a backport of OpenSSL, but I'm extremely reluctant to do so for Launchpad production since that would mean tracking security updates ourselves, with OpenSSL being something that frequently gets security updates. I'm working on a PyNaCl-based approach instead.
