Ok. By the way what about the issue described in
[PATCH v2 09/10] qemu: fix race on legacy block completion and quering stats
Are modern blockjobs have similar?
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.
