Ouch! Sorry, I forgot a detail here. This can also be another form of
NULL problem. For example, socket.socket.getservbyport() takes an
optional "protocol" argument. Internally its default value is NULL.
But there's really no good static string that we could use for the
default. Guido specifically suggested accepting None here to mean "use
the internal default" should be fine. But again this is a change, we're
in beta, etc etc, discuss.
