I've made the changes to use bytes, and updated the code with recent
changes. Issues it still faces:
- Buffers: It won't compile on Python 3 with references to old-style buffer
methods (e.g. PyBuffer_FromObject, Py_END_OF_BUFFER). This is the remaining
bit commented out. The new MemoryView method isn't in Python 2.6 (it comes
in with 2.7), so that falls over at runtime with the section commented out.
- There's a circular import between zmq/core/socket and zmq/core/context,
which goes into endless recursion when trying to import either of them in
Python 3.
