Summary0005177: Gc.compact does implies Gc.full_major
DescriptionThe doc for Gc.compact says: "Perform a full major collection and compact the heap."

However, reading the implementation in byterun/gc_ctrl.c, one can see that compact does not do the same set of operations as full_major:

  caml_empty_minor_heap ();
  caml_finish_major_cycle ();
  caml_final_do_calls ();
  caml_empty_minor_heap ();
  caml_finish_major_cycle ();

  caml_empty_minor_heap ();
  caml_finish_major_cycle ();
  caml_finish_major_cycle ();

I believe it would be a good idea to do the extra final_do_calls/empty_minor_heap in compact as well.
