Actually, your being on MS-Windows does explain what you see, because
the way C-g is processed is system-dependent. When I said "this is
not supposed to happen", I assumed you were doing this on GNU/Linux or
another Posix platform.
Indeed, on MS-Windows this is expected behavior: pressing C-g in the
above scenario will set the quit-flag, and the loop will then quit.
To prevent that, you need to use this simple technique:
(make-thread
(lambda ()
(let ((inhibit-quit t)) ;; <<<<<<<<<<<<<<<<<<<<
(cl-loop
while t do
(progn
(thread-yield)
(sleep-for 30))))))
Btw, my recommendation is to bind inhibit-quit non-nil around the
thread functions in all cases, if you want background thread to never
be interrupted by C-g and the like.

Sending this as a bug report per Eli Zaretskii's mention that it may not be expected behavior (https://www.reddit.com/r/emacs/comments/1fbkkii/comment/lm3boja/). Repro recipe: - emacs -Q - `C-x 3` and run `list-threads` in the new window, then return to the older window - `M-:` `(make-thread (lambda () (cl-loop while t do (progn (thread-yield) (sleep-for 30)))))` and wait for the new thread to yield to the main thread. - `C-g`. The new thread disappears from the `list-threads` window. Note: While I am admittedly on Windows, given this behavior is within the cooperative threads of the Emacs runtime (rather than actual Windows threads) I *really* doubt that has anything to do with it.
