Perhaps I am missing something from the previous discussions, but I
am having trouble understanding the "main packed ref cache" part of
the above.  "main" as opposed to...?

"main" as opposed to "submodule".

I see.

No, the scenario would be that a git process wants to change a reference
in a submodule directly, as opposed to starting another git process
within the submodule, as I believe is done now.  Maybe it's too
far-fetched even to consider...

Perhaps.  But the "singleton lock because we only handle main packed
ref cache" does not prevent us from doing so later, so I think v3 is
OK.

Thanks.
