Would the BaseHttpServer module that comes with Python work for the purposes of
this module's functionality?

Just noticed that the link doesn't work. This does:

Not for our purposes. Its pretty hard to code path handlers with the default
module. Since this component will be touched everytime anyone adds a new test,
I'd like it to be as easy as possible. Using a WSGI framework like CherryPy will
help. CherryPy is already in Chromium here so we can use it too -

Please run gpylint on this module. That should identify some import and
indentation cleanup.

Done on most things. It still complains about invalid method names in the
classes but thats cherrypy specific so can't be changed
