I've fixed this on the Zope 2.8 branch and HEAD, thanks for the bug reports!

TemporaryStorage isn't part of ZODB/ZEO, it's part of Zope.  I don't know much about it.  I think Chris McD already knows about this, so assigned to him.  See his Issue 1526, which I expect is the same thing.

I set this up in a Zope 2.7-head sandbox successfully:  the only
change I made was to give the <zeoclient> section for the
'temporary' mount a different name ("tempstorage") than the 'primary'
mount ('zeostorage').

Equivalent changes on Zope 2.8-head did lead to the traceback you mention on startup (I didn't try adding the mount point):

Setting up a fresh ZEO/Zope setup (a single mkzeoinstance and a single mkzopeinstance) and editing the ZEO config to add:

 %import tempstorage
 <temporarystorage temp>
    name temporary storage for sessioning
 </temporarystorage>

and the Zope config to add:

 <zodb_db temporary>
    <zeoclient>
      server 8100
      storage temp
      name zeostorage
      var $INSTANCE/var
    </zeoclient>
    mount-point /temp_folder
    container-class Products.TemporaryFolder.TemporaryContainer
 </zodb_db>

After starting up, the App doesn't have a temp_folder, and when I try to add the mount point, I get:

 Error Type: AttributeError
 Error Value: TemporaryStorage instance has no attribute 'loadEx'
