Yes, that's needed. I have also no idea how to fix. But I know that the
proposal to disable keyboard reading for all threads but the main one is
not working; see my example in bug#32426.

Perhaps we need this also for other events, D-Bus and file notifications
come to mind.

I fear I'm not the best one to reanimate this discussion. Keyboard
handling in Emacs is terra incognita for me.

Best regards, Michael.
