I'm not sure that is the case. As far as I know offhand,
[Gc.full_major] won't cause memory previously occupied by Caml heap
pages to be returned to the operating system (and so you'd still
see it allocated in top). You would need to call [Gc.compact],
which is potentially much more expensive, to achieve that effect.
