Then, coming back to my original question: any pointers on how
to debug that? Is there any documentation explaining what
component in Hurd implements AF_LOCAL sockets and how it all
works? Are there any tracing / debugging options one can apply
here (apart from rpctrace, which doesn't appear to tell me
much in this case)?
(Also, I'm unsure my problem is actually related to SCM_CREDS,
that's just the only special thing that's done here, which is
why I mentioned it.)
