xlib is based on xcb in the sense that libxcb owns the conection, and
xlib takes it when it wants it.  This approach has recently been
generalized, so it should be possible (in principle) for XHB to ride
on top of libxcb in the same way:

But I haven't looked into this approach too deeply, though.  Questions
I don't have answers to:

 + How do I get events/errors back into Haskell-land?
 + How do I get my FFI bindings to xlib to cooperate in all of this?

But it would be great if we could use native Haskell where we can, but
still call into C-libs where we can't.
