Yes, evidently your problem involves some code that I don't have, which e= xplains=20 why I can't reproduce it. If you can provide a way to reproduce your prob= lem=20 (i.e., C-g does not work) then perhaps we can fix it. > I reran similar code with emacs -Q, and it turns out I can stop it.

Yes, that's to be expected. Emacs is single-threaded, and if are running = Lisp=20 code it cannot respond to other keystrokes to run any other Lisp code; al= l you=20 can do is interrupt it with C-g.
