When using the Emacs cooperative threading system in a new project, I noticed that calling C-g results in quitting the background thread I create, even when those threads are yielded.
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.
