You need to tell the GC the address (outside the heap) where the Caml
value is stored, using register_global_root().
When the external data structure is no longer relevant, or is about to
be freed, call remove_global_root() to tell the GC that the global
root is no longer there, thus allowing the GC to reclaim the
corresponding Caml data structure.
