I, too, agree it's rare.  Rare enough to justify leaving the vulnerability
open on Windows, indefinitely?  I'd say not.  Windows itself has been pushing
steadily toward better multi-user support over the past 15 years or so.
Releasing software for Windows as though it were a single-user platform is
backwards-looking.  We should be a model in this area, not a straggler.

One option that would simplify things is to fix only non-Windows in the back
branches, via socket protection, and fix Windows in HEAD only.  We could even
do so by extending HAVE_UNIX_SOCKETS support to Windows through named pipes.

Using weak passwords on Windows alone would not simplify the effort.
