I'm beginning to wonder whether Zope 2.7 shouldn't require Python 2.1.3 rather than 2.2.2. The original motivation for requiring 2.2.x was to allow easy backporting of Zope 3 components, and that is no longer a goal. I've asked Brian to review the version decision in this light.
Without python 2.2 zope will continue to harbor remotely exploitable zlib-based memory exhaustion attacks.
