I know that it's not just the 4 line function, etc. However, there is
currently
no way to find out if that non-standard setting has been changed. Is it
safe to assume
that we will always have a "default" unix socket that we connect to if no
hostname is specified?

However, as I said a couple of messages back, this isn't gonna fly, based on
your objections,
so I'm gonna drop it.
