This falls under the category:
  'Be careful what you ask for. You may just get your wish' 

I finally realized that this behavior is because the getattr
behavior that I was lobbying for about a year and a half ago has
at least been partially implemented! (concerning what sorts of
requests are transacted and some other issues).  I figured my
application was just too far out in left field for Zope and gave
up on it about a year ago. The description of the getattr changes
I read didn't seem to indicate these types of changes were made.
Maybe I missed the crucial parts though.

Is there a detailed discussion of the changes made to getattr
behavior anywhere? I plowed around and couldn't find one.

Thanks
