    inet: return EHOSTDOWN if we cannot resolve an address in time
    
    This allows programs to make informed decisions about what to do
    if anything goes wrong trying to resolve the address.
    
    For example, ping(8) now reports sendto: Host is down, which is
    more useful than not reporting anything.
