By the way, yesterday I wrote some tests for Python 3.x and I found a
possible problem (only indirectly related to WSGI, however).

The example consists in a simple client -> proxy -> server, where the
client and server are in Python 2.5 and the proxy in Python 3.2
(compiled from tip, some time ago).

Here is the proxy:
http://paste.pocoo.org/show/202212/

The application fails, if cookie contains non ascii character.
The reason is that, for reasons I do not understand, http.client encode
request headers using us-ascii, instead of iso-8859-1.

The offending code is:
