Paolo Bonzini bae8196d9f blockjob: introduce .drain callback for jobs ... This is required to decouple block jobs from running in an AioContext. With multiqueue block devices, a BlockDriverState does not really belong to a single AioContext. The solution is to first wait until all I/O operations are complete; then loop in the main thread for the block job to complete entirely.
