This is weirdly specific. Can we accomplish the same thing with existing tools?

E.g., could:

  git cat-file --batch-all-objects --batch-check='%(objectname)' |
  shuffle |
  head -n 100

do the same thing?

I know that "shuffle" isn't available everywhere, but I'd much rather see us fill in portability gaps in a general way, rather than introducing one-shot C code that needs to be maintained (and you wouldn't _think_ that t/helper programs need much maintenance, but try perusing "git log t/helper" output; they have to adapt to the same tree-wide changes as the rest of the code).
