But then, is that space not reclaimed if a GC occurs and it's not being
used? Or can the Mac heap only increase in size?
I believe it is only reclaimed if the Lisp does a GC and still does not
have enough memory for the pending allocation request. That is, it will
only be reclaimed if it absolutely has to.
