Thank you very much for a fast fix/replacement of Transience :)

I installed new Transience.py. During my little test it works fine.
But real test will be on Monday when students start logging in as complete
classes, sometimes there are hundreds of them logging on simultaneously, 
so we will see. 

I copied original file, so in case of problems, I will put it back 
and restart Zope.

I will report if any problem occurs.
