There are a lot of systems where every DNS lookup has to timeout on the IPV6 lookup, thus IPV6 must be disabled. ... or the network infrastructure should be fixed, really.
Yes, in principle. Practically, more often than not the network infrastructure is not under your control (especially when using a notebook and travelling) and I can tell that having to await those timeouts _is_ painful.
One common cause of possible timeout delays is badly configured IPv6 router that advertises an IPv6 default route on the local network without providing the connectivity or sending proper ICMPv6 Destination Unreachable messages.
Or a route/DNS server that does not respond to AAAA requests but let's them run into a timeout. Yes, that sucks.
