Sheepdog tree already has codes to process sheepdog request
asynchronously (lib/net.c, lib/event.c, etc), so it looks easier to me
to implement an AIO client library in Sheepdog project rather than
recreate an async block driver in qemu.  But I'm not against moving to
the async driver as the first step.
