Yes, that's more or less the direction I was thinking of. I'm just
polishing my patch, will push it later today. I still keep the event
name sleep-event; we can change it later to system-event. But it should
be sufficient for now, for your tests and proposed patches for review.

What I'll appreciate is, if you could write down what system-event would
be good for, and which attributes a (system-event ...) event shall
carry. However, this is rather a discussion for the emecs-devel <at> gnu.org
ML, in order to get more attention from the Emacs developers.
