Re: [Libguestfs] [PATCH 1/4] ocaml: Use generational global roots.

These are considerably more efficient than ordinary global roots, but with the caveat that the program is not allowed to modify them without calling a special function. We don't modify them, so this change is safe. This requires OCaml >= 3.11, but we have that on RHEL 6 (since we dropped support for RHEL 5).
