[issue34759] Possible regression in ssl module in 3.7.1 and master

[Nathaniel Smith]

New submission from Nathaniel Smith <njs at pobox.com>:

Hey Ned, we just noticed that since a few days ago the trio testsuite is failing on 3.7-dev (but not 3.7.0), in a test checking an obscure feature in the ssl module: https://travis-ci.org/python-trio/trio/builds/431291929

And I just reproduced the issue locally with a build of the 3.7 branch HEAD, so somehow whatever is happening is definitely new in 3.7.1.

It could just be a bug in the test or something, I don't know because I haven't debugged it yet (I'll do that now). But with 3.7.1rc1 imminent I figured you'd rather know earlier rather than later.
