Hi list,
I have been working on a custom git server where the sha values
required to respond to a ls-refs command can occasionally be expensive
to compute.

Almost certainly the expensive part of ls-refs is actually traversing
the references, not parsing the objects they point at and determining
their hash.

Incidentally, we had a discussion recently [1] that resulted in some
patches that make it so that ls-refs often only has to read through part
of the refs in your repository, not all of them.

It would be a great improvement of user experience if it was possible
to show progress to the user while this is happening.

It's possible that that might help, but honestly I'd be surprised if
there was a real use-case that needed it (especially after the patches
that I mentioned which should make it fast enough that you don't have to
care :-)).

Thanks,
Taylor
