I'm quite sure I did. But that was on Windows, where C-g is less
powerful than on Posix platforms (since keyboard input is not
interrupt driven). So it could be that what you can interrupt on
GNU/Linux, I cannot on Windows.

Let me know if you need any further help.

That's good, because I needed to kill that session in order to rebuild
Emacs.
> Can you restart this Emacs session?
No, but I can start another and do the same (i.e. wait for it to hang
in the same way). The problem is reproducible in my configuration.
But I think it would be better to wait for you to fix that problem you
are zeroing in, and then see if it also fixes my hangs.
Thanks.
