I'm generally in favor of less magic and less fragile, and don't mind a
bit of slower to get that. I wonder if you have any quantitative
estimate, but I guess it's 9 copies of the unpacked python distfile,
minus the bits that are needed, so maybe 9*0.98. Guessing from 'xzcat'
size on 3.8, that seems like 738 MB of extra write load for a full bulk
build, about 80 MB per package above. I'd expect most people building
more than a few to have a decent-sized tmpfs and workdir on it, so I
would guess this doesn't really hurt.
Is that how you see it?
