If the idle thread was doing the suspending then the inactivity timer by it's self could block suspend. As long as the idle thread was setup to check for timers. I'm sure that _isn't_ the point your trying to make. It just makes gobs more sense to me that the idle thread does the suspending .. Your idle, so depending on how long your idle then you suspend.
