2071 * In an ideal world we would unconditionally create a new BlockBackend for

2073 * take effect on the exact BlockBackend whose name the user passed instead
2074 * of just on a temporary copy of it.
2075 *
2076 * Another problem is that deleting the temporary BlockBackend involves
2077 * draining all requests on it first, but some qemu-iotests cases want to
2078 * issue multiple aio_read/write requests and expect them to complete in
2079 * the background while the monitor has already returned.
2080 *
2081 * This is also what prevents us from saving the original permissions and
2082 * restoring them later: We can't revoke permissions until all requests
2083 * have completed, and we don't know when that is nor can we really let
2084 * anything else run before we have revoken them to avoid race conditions.
2085 *
2086 * What happens now is that command() in qemu-io-cmds.c can extend the
2087 * permissions if necessary for the qemu-io command. And they simply stay
2088 * extended, possibly resulting in a read-only guest device keeping write
2089 * permissions. Ugly, but it appears to be the lesser evil.
