Please note that due to the semantics of the commands 'block-job-cancel'
and 'block-job-complete' at least in case of the drive/blockdev-mirror
job are technically blockjobs of it's own since they may fail or finish
in an unbounded amount of time and the actual return value on the
monitor does not reflect the result of the operation itself.

It would be very helpful if qemu treas them as such.
