Some of the dtml methods being cached have dtml namespace cache keys set 
(no request vars are used) and appear on all accounts to being working 
as expected, with the expected number of enteries for these dtml 
methods. Most create one entry, a few others create anywhere between 
5-20 enteries as the dtml keys change as I would expect. The dtml vars 
are set by dtml-let statements before the method or script is called.

Do you mean to just move the "transient object container" to the zope 
root folder? What is bad about doing this?
