Here is the version of wsgi1to2 that I have used:
class Context(object):
     def __init__(self):
         self.response = None
         self.headers  = ()
         self.buf = []

     def __call__(self, response, headers):
         self.response = response
         self.headers  = headers

         return self.write

     def write(self, buf):
         from warnings import warn

         warn('write callable is deprecated', DeprecationWarning)
         self.buf.append(buf)


def wsgi1to2(application):
     """Converts a 1.0 app into a 2.0 app
     """

     import sys

     # Some applications require argv
     sys.argv = ['wsgi application']

     def wrapper(environ):
         context = Context()
         results = application(environ, context)

         if context.buf:
             buf = context.buf + list(results)
             return context.response, context.headers, ''.join(buf)

         return context.response, context.headers, results

     return wrapper


I have managed to run the Mercurial web application.
It is very slow on mod_wsgi, since it uses the write callable and is CPU 
bound.

With Apache Bench (n = 1000, c = 50), I get:
- 27 requests per seconds with the builtin server
- 20 requests per seconds with mod_wsgi (and 2 worker processes)


However with mod_wsgi my system load is above 2, with the builtin server 
it is over 6.
