Yeah, it's hard to test this stuff without either opening up security
hazards or making unwarranted assumptions about the local network setup.
I think that the standard regression tests only use Unix-socket
communication (except on Windows) for exactly that reason, and that makes
it hard to do anything much about regression-testing this feature.

Check. Proposed doc patch attached. (Only the last hunk is actually
specific to this patch, the rest is cleanup that I noticed while looking
around for possibly-relevant text.)

Don't really see the value of either ...
