[Zope] Core Session Tracking 0.8 and Zope 2.4.x?

Is Core Session Tracking working with Zope 2.4.x? I had a really quick go last week with 0.8 and it barfed about something of a looping over non-sequence in some method deepdown called _vw or something. Haven't had time to experiment with it yet, but now I'm more in the planning kind of stage and trying to find out about future product compabilies. Yes, I searched the mailing list and found nothing.
