I saving session in "req" anyway, do this:

>      sess = Session.Session(req)
>      if sess.is_new():
>          # get settings from cookies (using Cookie)

def home(req):
     if not hasattr(req,"session"):
       req.session = Session.Session(req)
     if req.session.is_new():
     return apache.OK

def english(req):
     if not hasattr(req,"session"):
       req.session = Session.Session(req)
     req.session["language"] = "en"
     return home(req)

Shouldn't need to unlock session then and same session object used.
