Comment 3 for bug 1842509

The Python extension modules xorn.storage and xorn.guile are specific to Python 2. Instead of making them specific to Python 3, I'd prefer to re-write them in a way that is independent of the Python interpreter used.

I have so far ported xorn.storage to cffi, which makes it a pure Python module. Now I'll have to tweak it until all tests pass and then port xorn.guile.
