Why is it safe to drop this?
The memory API will sync the dirty bitmap once it becomes invisible.
(that's the whole point - it can be made invisible by something outside
the cirrus card's knowledge).
Note - with kvm, there is still a race between syncing the bitmap and
removing the region. However that is a bug in the kvm API; it is not
possible to work around it in qemu.
