Regular sockets cannot be used because they cannot pass file descriptors.

As you know, this was discussed before the SMP code was written. The
thread name is "SMP: inter-process communication". In summary, I am sure
there are Windows-specific APIs that pass/share descriptors, but our
attempts to get details from Guido have failed.

If you do not hear specific suggestions, researching how ACE and Apache
httpd share descriptors on Windows may help. Also see:

Needless to say, we would need to wrap the UDS vs WindowsAPI distinction
in some common layer so that the callers do not have to know the difference.

Thank you,

Alex.
