Looks like TravisCI isn't accepting new requests for OS X test builds. I'm not sure how to get this tested as there's no Ubuntu OpenSSL 1.0.2 package either.

Final error arises from test_set_tmp_ecdh when it calls context.set_tmp_ecdh(curve) for EC curves Oakley-EC2N-4 and Oakley-EC2N-3.

@exarkun It's not clear to me why the Context.set_tmp_ecdh() call for Oakley-EC2N-4 and Oakley-EC2N-3 cause an OpenSSL exception but it looks like it's also not being raised properly either since it's the TestCase.tearDown() cleanup that is discovering the exception.

After a discussion with Paul I think we should not do that. pyOpenSSL should offer as little abstraction as necessary and since this bug has been fixed in 1.0.2a, we shouldn’t add baggage to our codebase.

Thanks for this and your responsiveness! Please revert the one change and we’re good to go if the CI stays green. :)

The fix that will stop the notAfter bug has not yet shipped (should be in 1.0.2b actually), but we'll merge this now since it shows the issue. Thanks again!
