Please do. Correct me if I'm wrong, but the timeout of the Timer won't
be precise; that clearly is undesirable. It also seems that this would
be easy to correct: If endtime-_time() < delay, you have to decrease

What then is left is that cancellation of the timer may take up to a
second, that should be documented. I think it is possible to do better
than that on some systems; maybe somebody feels inclined to improve
the code on, say, UNIX.
