      If you run the following command, it will print the 20 largest files in our git history:

      $ git rev-list --objects --all |   git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' |   sed -n 's/^blob //p' |   sort --numeric-sort --key=2 |   cut -c 1-12,41- |   $(command -v gnumfmt || echo numfmt) --field=2 --to=iec-i --suffix=B --padding=7 --round=nearest | tail -n 20

      Several of these are coredumps that were presumably accidentally committed. They were later deleted (eg, here), but that only removes it from the current version, it doesn't actually remove it from history. So now every clone of the mongo repo needs to carry that file around in .git forever. We should add a pattern for core dumps to our .gitignore to prevent this from happening again.
