Takes me about 9000 bytes to encode/decode RFC 1035 with error checking,
plus logic to try the nameserver list until I get an answer, with automatic
fallback to TCP upon response packet truncation. The code is probably
multithreadable, although I haven't tried.
Does not include libc overhead. On SysV boxes all the TLI garbage will
probably take even more overhead.
