I know.  That's why I pushed and pushed to get the branch merged
"early" -- I knew _something_ would go wrong, I just didn't know what
<wink>.

Jim and I knew about the ZODB-3.4-in-Zope-2.8 plans for quite a while,
but I doubt that even Brian was aware of them.  There's no way you
could have known -- not your fault.

It is, but it would go faster if I did it.  I rewrote all uses of
get_transaction() in the Zope and Zope3 trunks on Monday, so I'm in
practice.  For the most part they amount to no more than what Jim
said, but there are trickier cases than commit().

Suggestion:  I make a new copy of

     Zope3/tags/ZopeX3-3.0.0-Zope-2.8-pr1/src/zope

stitch that into Zope trunk (change the lib/python svn:externals to
point to the new copy), do all the get_transaction() edits there, and
repair the IDataManager glitch there too.  This could easily be done
before lunch today (my time <wink>).

If people are agreeable, help me pick a name for the new copy; I have
no idea what the "pr1" is supposed to mean in the current name, but
would like to stick to whatever naming convention is in use there.

That's right -- it's almost all under lib/python/zope/.

Above, I'm volunteering to do the latter.  Somehow I get the
impression that sticking an unplanned X3.0.1 release on the critical
path for Zope 2.8 wouldn't go over well here <wink>.
