I believe 7c79df11c7a9d938ed9b48e00c4366da95301d4b fixes a race
condition that these tests were showing: ‘herd stop root’ can return
before the shepherd process has terminated.

Could you try again?

For AArch64, what machine are you using, with what CPU?  There’s a
Guile (?) bug manifesting on the OverDrive 1000 that causes more or
less random test failures, unless you set GUILE_JIT_THRESHOLD=-1:
