IMO, there should rarely, if ever, be changes on the trunk that aren't
in the most recent known good ZTK distribution.
The way I've done this is:

- Check out the ZTK
- Check out a working copy of the package(s) of interest and
  build as develop eggs with the rest of the ZTK.
- Hack till I'm happy and the ZTK tests pass.
- Check in changes to the packages and make new releases.
- Update the ZTK buildout to use the new releases and test again.
- Test with multiple Python versions.
- Check in changes to a branch of the ZTK.
- Run tests of the branch on windows. If they pass, merge the ZTK
branch to trunk.
  With buildbouts, ideally there'd be a stage branch we could merge
to, wait for the
  buildbots to to their thing and then merge to trunk when tests pass
on all platforms.

I really think we want to avoid long-lasting unreleased trunk changes
to or long-lasting
newer releases not in the KGS for ZTK packages.
