That would still mean you could get into a broken state for serving
fetches, but you could at least get out of it by running "git repack".

I was puzzled by this "broken state" statement. But you were right! I
focused on the repack case and forgot about fetch/clone case. I will
probably just drop this patch for now. Then maybe revisit this some
time in fiture when I find out how to deal with this nicely.

Here's a sketch of the "separate array" concept I mentioned before, in
case that helps. Not tested at all beyond compiling.

Brilliant! Sorry I couldn't read your suggestion carefully this morning.
