Review Comment:
Right, I understand that part; my question was: if it's the act of mapping
the file that allocates virtual memory, and there's no deduping, then in theory
even with a limited number of files per segment, and even if segment
generations don't change at all, if you re-map the files enough times on the
same Arena without closing/de-allocating, you could still exhaust resources.
