Running it when it's not needed will indeed lower performance,
but not running it when it's needed will be a big loss. Maybe
we should do a run_task_queue(&tq_disk) whenever we're (almost)
running out of request slots?
Jeff saw a definate improvement in the performance of his system
when running tq_disk...
