The kernel just gets told to suspend by writing to a file in syfs. This is done typically by pm-suspend. When the pm-suspend command returns, the computer is resumed. In this way, upower emits a sleeping signal shortly before calling pm-suspend, and also emits a resuming signal when the command returns.
