It might even have one or two of my own bug reports in there. :-) I haven't tried so-long-mode (it seems to have become available only with emacs-27), but it appears from its description that it would also DTRT in my particular case. > Do you have reason to think this is Cygwin-specific?

(*) I never use the console and I have seen exactly the same problem in emacs-X11 (with DISPLAY on a Linux box) and emacs-nox (both over ssh an in mintty locally). I don't have another system with emacs-27 yet, but I expect that to be unrelated to Cygwin.
