I've applied itojun's patch, with slight modifications.

Itojun, I have a few questions on this documentation, though:

You write that socket.herror and socket.gaierror may both take either
a string or a pair of error number/message. Is this correct, or was
that a cut-n-paste error from socket.error?

You also write that socket.gethostbyname may raise socket.herror. Is
this true? It seems that you'll always get socket.gaierror instead.
I've changed it to say that gethostbyname_ex may raise herrors.

Anyway, thanks for the patch.

Regards,
Martin
