Modern blockjobs are started with '"auto-dismiss": false' so if you get to the monitor before the thread completing the blockjob finishes it, qemu still reports the status for the job. The completion is done inside a 'MODIFY' job lock, so other thread won't be able to get to the monitor in the time between the job is dismissed in qemu and the XML/definition is updated.
