    Allow scheduler tasks to request longer wait periods

    This change allows a scheduler co-routine to yield an integer n, such
    that only every nth call to TaskRunner.step() results in the co-routine
    being advanced. We'll be able to use this to selectively slow down
    polling of resources where and when we know it doesn't make sense to
    poll every second.
