Antoine, I think we have to make a decision here: I'm still -1 on changing PyUnicodeObject to be a PyVarObject, but do like your experiments with the free lists. I also still believe that tuning the existing parameters in the Unicode implementation and pymalloc would give a better performance gain than what your patch achieves. Setting KEEPALIVE_SIZE_LIMIT to 32 would be a first start in that direction. However, if you insist on changing the PyUnicodeObject structure, I'll have to reject the patch.
