Is there anything I can do to speed this up? Is something about my code still
in a known bad state? Or is all that is left the ambiguousness of POSIX.1-2008
regarding errors of getaddrinfo(), which makes glibc and musl-libc interpret
it differently? Or is just my reading of the spec wrong and musl-libc got it
