After all, Emacs is still a text editor, isn't it? Key strokes and mouse
events are the most important events, I believe.
As rule of thumb, I would discriminate all events, which can aarive as
burst, and which are already known to be lost sometimes. D-Bus and file
notification events. If we classify other events into this category - no
problem.

Yep. And Ian is also on the same way, AFAIU.
Best regards, Michael.
