[Zope] temp_folder not MountTemporaryFolder?

[Chris McDonough]

/temp_folder is a "mount point" (see your zope.conf file).

Whether or not you put a session data container inside of a temp  
folder, you may get better conflict-related performance out of  
"faster", a drop-in replacement for the stock Zope sessioning  
machinery...  see http://www.agendaless.com/Members/tseaver/software/ 
faster/  (but you might not, it depends on the sessioning access  
pattern).  In particular "faster" is much better conflict-wise when  
sessions are accessed but not changed in the course of a request.
