Comment 6 for bug 1891158

From IRC:
[13:34] <cpaelzer> Laney: ha - timeout = 1 on x86 triggers the same warnings/erorrs, but NOT the hang of the builder
[13:34] <cpaelzer> https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/4200/+build/19818311 is an example
[13:34] <Laney> interesting
[13:35] <Laney> perhaps riscv64 does process reaping differently
[13:37] <wgrant> Laney, cpaelzer: dbus-test-runner is what generally gets stuck, I haven't worked out why.
[13:37] <wgrant> But there are a couple of packages that were consistently hanging because it didn't die for a while. But they seemed to eventually fix themselves by around maybe September.
