Kevin, could you please add Paolo's patches to your block queue?

I did not review each single patch in detail, but the resulting
code looks sane and much better (and shorter) than the current code
(a little like my original code before I had to add asynchronous
I/O support).

As Paolo already tested with qemu-iotests, I did not re-run those
tests.

Thanks,
Stefan W.
