The patch is intended to be a general ZODB improvement that enables ZODB 
to interact in a natural way with data stores that already provide MVCC 
semantics.  It does this by allowing the storage to bind a separate 
storage instance to each ZODB.Connection, rather than attaching all 
ZODB.Connections to a single storage.  The patch also allows the storage 
to provide object invalidations through polling.

I hope the patch, or a modified version of the patch, will be accepted 
for inclusion in ZODB 3.9.  A monkey patch version is possible, but I'm 
trying to avoid that.
