When I create a fresh virtualenv, pip freeze shows that I have a couple of packages installed even though I've not installed anything into the environment. I was expecting pip freeze to return empty output until after my first pip install into the environment. wsgiref is part of the standard library isn't it, so why does it show up at all?
