trace2 data isn't sent to users. So having read this after I took a look
at the updated round, I am glad that you pursued the approach that you
did :-).

We're depending on the loop in open_pack_bitmap() seeing packs in an
order compatible with the output of 'ls -tr' here. In other words, for
this test to pass, we care very much that the pack we collected as
"$ignored_pack" is seen *after* the pack that we designate as
"$open_pack".
Does that help?
Thanks,
Taylor
