Yeah that's a funny hack. I don't think it's required though, but I'm just
running through some more tests.

I think I found an improvement with the thin archives as well -- we were
still building symbol table after removing the s option (that only avoids
index). "S" is required to not build symbol table.

I'll send out an RFC on a slightly more polished patch series shortly.

Thanks,
