Sorry, I did not know that Emacs would return pages rarely. I figured it
would be somewhat common, if you have multiple, dead GBs of heap laying
around (as in the linked reddit post). Such a thing seems like a token
that you should give some of that back to the OS. But, that is just my
opinion at face value of the situation and I admittedly lack experience
in implementing this sort of thing.

Well, again, which source file(s) may I poke at to see this sort of
stuff in action myself?

Thanks.
