If it's a single 1GB chunk, it'll most likely be returned (tho there are
unlucky build-configurations where that might happen, and I believe such
situation has unwittingly been in common use for Emacs-25.1 under
GNU/Linux, IIUC).

In the reddit thread, the 1.5GB is completely unexplained, so it's hard
to say anything intelligent about it.
