I know what the doc says. I'm asking if anyone has actually tested
this.

*If* it is true, it *is* broken. "Emacs idle-time" and "user
idle-time" *should* to be the same (according to the Emacs Lisp
documentation).

    Emacs can do various things while idle: garbage collect, autosave
    or handle data from a subprocess. But these interludes during
    idleness do not interfere with idle timers, because they do not
    reset the clock of idleness to zero. An idle timer set for 600
    seconds will run when ten minutes have elapsed since the last user
    command was finished, even if subprocess output has been accepted
    thousands of times within those ten minutes, and even if there
    have been garbage collections and autosaves.
