bug#75275: 30.0.92; `make-thread` bug on macOS 15.2

[Stefan Kangas <stefankangas@gmail.com>]

I have run into a bug with make-thread on macOS 15.2, running on an M2.

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.

Running under lldb, I see the following lines get printed over and over:
