Correct. Implementing it this way does mean savevm can effect the guest VM state (it causes all pending IO to complete immediately). However this should be safe, ie. it could occur be chance anyway, and qemu isn't deterministic to start with. Trying to make async AIO restartable is IMHO not worth the effort at this point.
