title: Python 2.5 (PyPy) compatible web server / framework
body: <p>I'm looking for a simple Python framework/library for creating a website run using PyPy.</p>
  
  <p>So far, I'm using web.py, so that's the feature set (a bit a templating, sessions, input processing, that's it) I need for this project. Very minimalist, if possible.</p>
  
  <p>web.py is not unfortunately not compatible with Python 2.5 (at least the Python 2.5 implemented by PyPy).</p>
  
  <p><em>Edited to add</em>: The solution should be able to run applications (light on the views, models, etc., heavy on the computation) reasonably well. Security is not an issue, but on my machine, every 20th or so request of the integrated web.py server didn't get answered, leaving a blank browser page. This would be unacceptable.</p>
  
  <p>Is there something like this?</p>
