If oldStyle converts the classes into hybrids, then it's broken.  Hybrids don't follow the semantics of old-style classes.  So this won't happen.

My guess is that this is an insignificant micro-optimization and that pypy has gotten better at optimizing hybrids since that caution was written.  That said, we're really bad at paying attention to speed.twistedmatrix.com <http://speed.twistedmatrix.com/> and we really need a way to see pre-merge performance metrics rather than just a graph over time.
