Great. FWIW, this is the most similar version to the one we played with in 2013. I have an alternative one that keeps the single address_space_rw API, and checks if you have the iothread mutex using thread-local storage. The reason for that is that I would have to introduce address_space_map/unmap_unlocked too, which I didn't really like. Also, in the not-so-long term we want the same code (e.g. SCSI layer) to run in both locked and unlocked mode. What do you think? Paolo
