    If the only two tasks in the system that wants the kernel lock are the
    wakenup task and the current-running task, then rescheduling the wakenup
    task in _place_ of the current task will work _fine_. There _won't_ be any
    contention of the lock simply because the current task will go offline
    waiting the next schedule sleeping in the _run_queue.
