My original code didn't use auto-finalize and auto-dismiss, but it obviously makes sense given your addition of it for all other block jobs. (We've improved a lot in the code base since my first proof-of-concept a year ago...)

I also like that you added this in the monitor code (whereas I had hacked it in via direct calls in qemu-driver.c).
