+A workaround has been applied to the in-tree build backend that prevents
+Cython from hanging when ``libssh`` header files are missing
+-- by :user:`webknjaz`.
+
+The patch makes ``cythonize()`` single-threaded because :mod:`multiprocessing`
+gets stuck. The upstream will eventually fix this by migrating to
+:mod:`concurrent.futures`.
