We're experiencing a zombie outbreak:

```

over 1229 and climbing as I type.

It's git-annex version: 8.20210331-g1fb59a63a

I've now stopped and restarted the 'git-annex get', but without `--jobs 4`, and this time it appears to have two zombie git processes, but it's not increasing as it gets more objects.

I'm unsure how to debug what is wrong, so seeking guidance.

Tomorrow I'll start to see if I can reproduce with older/newer versions of git-annex.
