Sorry, I just meant that my 100 million-object case turned out not to
need all those objects, and I was able to prune it down. No code fixes
came out of it. ;)

Yes, though I think it would take a fair bit of surgery to do
internally. And some features (like bitmap generation) just wouldn't
work at all.
I suspect you could simulate it, though, by just packing your subset
with pack-objects (feeding it directly without using "--revs") and then
catting the resulting packfiles together with a fixed-up header.
At one point I played with a "fast pack" that would just cat packfiles
together. My goal was to make cases with 10,000 packs workable by
creating one lousy pack, and then repacking that lousy pack with a
"real" repack. In the end I abandoned it in favor of fixing the
performance problems from trying to make a real pack of 10,000 packs. :)
But I might be able to dig it up if you want to experiment in that
direction.

Are you looking at RSS or heap? Keep in mind that you're mmap-ing what's
probably a 1GB packfile on disk. If you're under memory pressure that
won't all stay resident, but some of it will be counted in RSS.

Yeah, that would be pretty invasive, I think. I also wonder if it would
perform worse due to cache effects.
