Right, I understand how that ends up with duplicate structs for each
pack. But how do we get a cycle out of that?

I think it may be worth doing that anyway. You can assume the hashmap
will behave reasonably.

But it would mean that the "multi_pack_index" flag in packed_git does
not specify _which_ midx is pointing to it. At the very least, it would
need to become a ref-count (so when one midx goes away, it does not lose
its "I am part of a midx" flag).  And possibly it would need to actually
know the complete list of midx structs it's associated with (I haven't
looked at all of the uses of that flag).

That makes things sufficiently tricky that I would prefer not to
untangle it as part of this series.

But now the internal midx writing code can never call close_midx() on
that, because it does not own it to close. Can we simply drop the
close_midx() call there?

This would all make much more sense to me if write_midx_internal()
simply took a conceptually read-only midx as a parameter, and the caller
passed in the appropriate one (probably even using
prepare_multi_pack_index_one() to get it).
