I am back from my vacation and am just starting to catch up on the
progress that you've made while I was away.

I haven't had much time to focus on your work outside of the
oe_map_new_pack() bug that you mentioned above, but I have spent most of
today looking at that issue. I am able to reproduce the flake, and
found/fixed a couple of small things along the way. But I haven't been
able to reliably patch the bug, even after replacing the call to
`add_packed_git()` (from `add_midx_to_pack()`) with a similar function
that looks for an existing pack in the `r->objects->packed_git` list
with a matching name.

I'll keep looking into this, and I hope to have a fix soon-ish.

Thanks,
Taylor
