Correct. Ocaml assumes (or knows which OS does) the OS will free all
resource at exit anyway. No point wasting valuable time doing a GC
sweep.
In case of custom blocks and finalize function I believe this to be an
error. Managing resources that the OS does not free (IPC tokens,
tempfiles, ...) is made much harder due to this.
