Boehm is only supposed to collect the C(++)land values. One can
register the OCaml-boxed pointers that refer to these values as
Boehm-GC roots, and deregister them (?) in the OCaml-finalizers for
the pointers. I don't see anything scary with this approach, provided
(?) is possible. Is the performance penalty as big as with smart
pointers?
