It's not a mere matter of putting back the code... The 3.x ssl implementation which was backported uses a slightly different approach from the 2.x implementation, so it's not obvious we can recreate an entirely compatible implementation of_ssl.sslwrap().

As a matter of fact, gevent's fix uses some frame locals hackery to lookup the caller's "self" variable, which means it probably won't work in the general case:
