OK.  Thanks.

Hi Eli.

Your patch solves one of the 2 problems:
After your patch
emacs -Q -l /tmp/test.el
with unmarked
(run-test)
starts the session.

The remaining issue:
while i have some of the threads created by `run-test'
still active, keep using the keyboard might crash the
X lib.

Unfortunately not.
If i change test.el as follows:
(that is, without `message' calls)
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(defun mytest ()
  (dotimes (n 10)
    (sleep-for 0.5)))

(defun run-test ()
  (dotimes (_ 50)
    (make-thread #'mytest)))

;; (run-test)
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
And then i start session:
emacs -Q -l /tmp/test.el

After some simple keyboard inputs i get another crash
with error:

X protocol error: BadWindow (invalid Window parameter) on protocol request 129
When compiled with GTK, Emacs cannot recover from X disconnects.
This is a GTK bug: https://bugzilla.gnome.org/show_bug.cgi?id=85715
For details, see etc/PROBLEMS.
Fatal error 6: Aborted

And backtraces:
