Cool. Most of the changes look reasonable at first glance. I'll see what I can apply on my side. We may get at least some of this into Cython 0.16 (which is close to release). > As expected, the example above is much slower on pypy, about 15x slower > than with cpython2.6. Given that XML processing is currently slower in PyPy than in CPython, I don't think that's all that bad. Users can still switch their imports to ElementTree if they only want to push XML out and I imagine that lxml would still be at least as fast as ElementTree under PyPy for the way in. > And I still get crashes when running the lxml test suite.
