[Zope3-Users] Anyone doing an ORM for Zope3?

Just wondering if anyone is currently or planning to produce any kind of
ORM for Zope 3?
I'm representing some rows of SQL data as Zope 3 objects and find I need
some kind of minimal layer. While I can issue SQL requests easily, in
Zope3 when receiving, validating and storing an add/edit form, Zope3
wants to write to my object attributes one at a time. I tried hooking
setattr and issuing UPDATEs for each attribute but its (a) slow and (b)
some combinations violate my table constraints.
What I need is something that accumulates the setattr operations and
hooks into the Zope3 transaction mechanism. Then when the commit
occurs, turn those into one multi-column UPDATE operation per object
modified. Something like a Persistence mix-in for SQL-backed data.
Or is there another approach people are using for RDB objects?
