Haven't managed to crash it yet, but every run complains:
got to shutdown of 10 with refcnt: 2
Refs being all dropped, calling forget for 10
terminate called after throwing an instance of 'fmt::v6::format_error'
what(): argument index out of range
unknown location(0): fatal error: in "unixdomain_server": signal: SIGABRT (application abort requested)
Not sure if that's causing it not to fail here.
