I am using new Transience.py, and my temp_folder is on Sessions.fs ZODB 
now. I have one problem with it - it does not seems that this way it 
deletes old expired Sessions. The number of objects grow and grow, and 
today we reached limit. I think I have to delete Sessions.fs every night 
and restart Zope. Is it expected expected behavior when using file 
storage? I was thinking that only problem of this kind of storage is the 
need to pack the database sometimes.
