The test was added for this bug: getaddrinfo returns EAI_SYSTEM instead of EAI_NONAME when the network is down <https://sourceware.org/bugzilla/show_bug.cgi?id=15339> So I think the return code from getaddrinfo matters here. We could switch to a namespace with disabled networking; this way, the test would perhaps be more reliable. I also think the test is wrong. EAI_NONAME indicates (negative) success, something that should not happen if networking is disabled.
