It's a couple of hundred lines, I'd guess - on reflection, it's probably
not enough to be too bothered about - so I haven't. I'll submit a
patchset in a moment implementing the first part of what we've been
talking about (converting the NBD driver to use the aio interface).

Assuming we can get this merged, I'll submit an IPv6 and a timeout=
patch too. It might also be worth adding aio support to qemu-nbd - we
use the canonical nbd-server binary, so it won't affect us directly, but
it seems a shame for the server to be behind the client's capabilities.
