I expect something like replacing "import ssl" with "from safestdlib
import ssl", same for other modules.

FYI I backported some Python 3.3 modules for Python 2.7 for my
Trollius project, and it was not so hard. For ssl.SSLContext, it's an
empty class, it's just a wrapper to ssl.wrap_socket() which raises
errors when unsupported features are used.

I wrote Trollius to port OpenStack to Python 3, not to defer the port :-)

It's not always possible. For example, the OpenStack projet still have
+30 dependencies which are not Python 3 compatible yet.
https://wiki.openstack.org/wiki/Python3#Dependencies

We are porting these dependencies, but it may still take one year to
port the whole OpenStack project to Python 3. Come to help us :)

Sorry, it's maybe not fair to take the worst example (OpenStack) :-)
