I see your point and agree in principle.  What bothered me about
slapd's handling of the above situation was the way it's reported.
What you get in the log is a rather dire-sounding

daemon: socket() failed errno=97 (Address family not supported by protocol)

I know it's harmless and should be ignored, but IMO it violates the
principle of least surprise, and should either be made more
informative, or eliminated altogether (e.g., by --disable-ipv6).  I
chose the latter since that's the easiest way in my current setup.
