I think you've made Chris' point for him: nothing about the application being tested *requires* that there be a ZODB connection open; Grok's design forces opening one unconditionally, which is a layer of complexity which *can't be turned off.* The "conceptual" overhead of each of the frameworks is at least as important as the performance overhead.
