Patch 4 fixes qemu-img and qemu-io hangs on weakly-ordered architectures. Patch 1-3 are related docs fixes and improvements.
This is RFC because it relies on the iothread being locked during aio_poll on the main AioContext. If I add assertions for this however I see a failure for test 267, so I am posting it as a preview before I debug that. The doc patches can also go in independently of course.
