Just noting that this may create new but short-lived problems for
developers on Windows (can't tell for sure until I try it; has to do
with PuTTY's "symbolic names", and the unlikelihood that any
Windowshead has "svn.zope.org" set up as a symbolic name now).

Since Zope doesn't "own" ZODB, I don't see how merging the branch has
anything to do with how ZODB gets stitched in.  Stitching in a _new_
ZODB is my problem, after the branch is merged (& I need the merge to
happen first, so that Zope3 (lib/python/zope) packages show up on the
trunk -- ZODB 3.4 can't work without them).

AFAICT, no stitching of ZODB took place when five-integration branch
was created.  For example, the log message for
Zope/branches/five-integration/lib/python/ZODB just says it was copied
from Zope/trunk:29468.  IOW, it just copied over the version of ZODB
that happened to be in Zope trunk at the time the five-integration
branch was created.

If people then made _changes_ to ZODB code on five-integration, they
should not have, and it will create problems.

But if they didn't, the ZODB code on five-integration branch and Zope
trunk should still be identical, in which case no code in any of the 9
ZODB directories should have any effect on the merge.

IOW, ignore ZODB entirely:  if the tests pass on the branch, they
should continue to pass on the trunk after the merge, since the ZODBs
on branch and trunk should be exactly the same right now.
