I think your ad-hoc test might be a little more compelling if it was
easier to understand, which is to say, maybe if your Perl oneliner was
on more than one line, or had comments, or was in a different language.
Although you explain it right after, we kind of have to take your word
for it.

One worry I had was that we might be painting ourselves into a corner
here if we did want to support the ability to do multiple progress bars
simultaneously (for example if we want to pull from multiple CDNs at the
same time when we're using promisor packfiles, and we expect those packs
to be large enough that we'd need to show a progress bar for each one).
However, I think the pattern - hang onto a pointer to the progress
objects, and complain if we get a signal and there are any still valid -
still holds well enough, so I'm ok with this change.

There are a couple patches in the middle which I didn't reply to, but I
did read them, and they were so tiny and mechanical that I did not have
useful comments to add.

Thanks, it's nice to see progress here (ha ha ha).

Preferably with the BUG() message nit below,

Can we make the BUG() message a little clearer? Even in the context of
the code, it's not clear that what this BUG() really means is "hey, you
forgot to call stop_progress on something" or "hey, you can't have two
progress bars at the same time". Even if you were to change the name of
'global_progress' to 'existing_progress_bar' or something, I think that
would make the message more understandable.
