My take on resolving this issue:

- - Having the package's *own* tests pass is the only blocker to checking
  in to SVN:  otherwise we get into a "gridlock" situation.

- - If trunk tests for another ZTK package begin failing becuase of trunk
  changes you make, that would indicate that the *other* package is
  borked (it shouldn't depend on your trunk).

- - If there is an outomated "compattest" buildbot which turns red due to
  your changes, then you probably need to be available to help fix the
  dependent package (or maybe update the one you have changed).

- - Once you are ready to *release* an update, run the ZTK tests with your
  released version, just to check for breakage.

- - Before checking in an updated versions.cfg to the ZTK trunk,
  incorporating your new relase, all the ZTK tests *should* pass.  If
  they don't, then you should be in the middle of fixing them, or else
  don't check in.

- - Before tagging a release of the ZTK's versions.cfg, all ZTK tests
  for the included versions *must* pass.
