I haven't so just speculating here ...
Can the BDW collector be told about areas of memory which it must
not examine?
There is a useful macro used inside the OCaml compiled called (IIRC?)
Is_in_heap(ptr) which can tell you if a pointer points to something on
the OCaml heap (ie. something to be ignored).
