I can reproduce the issue consistently both on emacs-30 and master by evaluating this in emacs -Q: (make-thread (lambda () (sleep-for 1)) "bug") This leads to Emacs freezing up completely within a fraction of a second. I have time to move point once or maybe twice before it gets non-responsive, let's say within a few tenths of a second.
