51 + connection = TimeoutHTTPConnection(host)
52 + self._connection = host, connection

Why does self._connection get set for sys.version_info >= 2.7 but not < 2.7?

Python2.7 adds support to xmlrpclib for HTTP/1.1 - specifically gzip encoding and keep-alive. To support the latter, make_connection needs to return the same connection if one is available. Our subclass does not do this (so does not support keep-alive) but the 'close' method added to the parent class expects it to be present so added that line pro-actively to prevent it from throwing an exception.

The code we'd need to add to the top of our make_connection method to support keep-alive (and not break python2.6) is as follows in case we ever want to add it:

        # Return an existing connection if possible for HTTP/1.1 keep-alive
        if hasattr(self, '_connection') and host == self._connection[0]:
            return self._connection[1]

<timrc> Cody, maybe we should add the self._connection line commented out with a note since it's not actually doing anything right now (or that's how I understood your comment)
<timrc> Cody, also do we want to remove the hardcoded python2.6 paths from at least bugsy/config/offspring-web.wsgi (and maybe bugsy/config/offspring-web.apache)? And along with that, do we need to update docs/install.rst at all?

OK, sorry, re-read and understand that it's expected to be there. Perhaps a comment? I would ask we take out the explicit mention of python2.6 from docs/installing.rst (or mention alternative packages for python2.7) and make a note that paths should be updated to python2.7 from python2.6 in the wsgi and apache files.
