Thanks for the explanation. This answers my question. Do you need me to file a bug for the ABI tag not changing in PyPy2, or will you take it from here?

I would like to confirm that in fact there is an issue: that the c-extension shared objects are incompatible. I am not completely convinced this is the case, at least my experimentation with NumPy proved it indeed is *not* the case for PyPy2. I am open to hearing opinions from others. Is there a concensus around whether we do need to change the ABI designation? I think this would also require recompilation of any CFFI shared objects on PyPy2. Matti
