(let ((start (current-time)))
(sleep-for 10)
(float-time (time-since start)))

That would return (about) 10.0, right? If so, time-since is not what
I need.
(My version of Emacs (20.7) doesn't have time-since, but I guess it's
the time-since function from Gnus.)

Is there a way in Emacs Lisp to find out the amount of processor time
(perhaps separated into user/system time) spent by Emacs?
For example, if there was such a function called processor-time, this
should return (close to) 0:
(let ((start (processor-time)))
(sleep-for 10)
(- (processor-time) start))
, whereas current-time would indicate that ten seconds passed
sleeping.
