Well, I've played with your example. As Eli said, `set-process-thread'
is not needed here.

With your original example, I could reproduce the problem, However, if I
call

emacs -l test.el -f test-threads

the problem does NOT happen. My .emacs is quite long, so I didn't bisect
in order to find out what makes the difference.

I have changed your example a little bit wrt `thread-join', see
appended. This version runs w/o any problem even if emacs is called with
-Q. Maybe this helps you to debug further.

Best regards, Michael.
