I would not advocate this. Ctypes is the kind of meta programming that is great
when it works but hell if it does not and it adds more dependencies.
I just had a discussion with Andrew about other tricks how to bring C constants
to the ML side in order to decouple them. I’m using it in my Polly library - it
might not be the solution for Xen but worth knowing.
