These 'bzzzzt' comments don't really apply to the async
interface, I think -- they're a kind of joke about the
fact that some of these commands which take a long time
on hardware are (were) completely synchronous in the
QEMU model and so the 'operation' is indicated as taking
place via the 'bzzzt' sound effect.
