============================
Since version 0.17, Cython has basic support for cpyext, the layer in
`PyPy <http://pypy.org>`_ that emulates CPython's C-API. This is

GIL handling
------------
Currently, the GIL handling function :c:func:`PyGILState_Ensure` is not
re-entrant in PyPy and deadlocks when called twice. This means that
