It will be used in backup, when moved on async block-copy. Note, that job_user_pause is not enough: we want to handle child_job_drained_begin() as well, which call job_pause(). Still, if job is already in job_do_yield() in job_pause_point() we should not enter it. iotest 109 output is modified: on stop we do bdrv_drain_all() which now triggers job pause immediately (and pause after ready is standby).
