Ah, sure. In that code, I didn't try to save cycles, but to provide
rather exact timing. Of course the tiny sleep makes sense.
This application had always lots of work, so this was not an issue.
The reason not to use sleep was granularity, because I wanted
to see a mouse event, quickly. Probably no problem with a small
enough sleep.
