I have some data that will not naturally live as an item in a folder.  If 
I'm using Zope, how do I establish a root for it?  The ZODB docs talk about 
how to handle a free-standing database, but I don't see info about how to 
use the one that Zope has already set up.  I recall there's some way to get 
a handle to the open database, but I don't recall exactly what.  Can 
anybody help me out?

If I use a class variable, will that be persisted automatically, e.g.
class MyManager(Persistence.Persistent):
        MyClassVariable = SomePersistentClass()
? (Actually, I'm not sure if it matters whether MyManager is a subclass of 

Or, if it is not automatically persistent, is there anything I can do to 
make it persistent so that it will obey the transaction boundaries coming 
from web requests?

Final question, which is distinct from the root objects issue: if I use 
Zope's Persistent List, will that avoid the problem of faulting in the 
whole list if I don't need it?  I am looking for a good way to keep a 
record of transactions.  ZODB's raw transaction recording is probably not 
quite right since it has the wrong granularity, it mixes a lot of unrelated 
transactions (it's only some I want), and I think it can get zapped if I do 
various database compactions and cleanups.
