2089 * In an ideal world we would unconditionally create a new BlockBackend for

2091 * take effect on the exact BlockBackend whose name the user passed instead
2092 * of just on a temporary copy of it.
2093 *
2094 * Another problem is that deleting the temporary BlockBackend involves
2095 * draining all requests on it first, but some qemu-iotests cases want to
2096 * issue multiple aio_read/write requests and expect them to complete in
2097 * the background while the monitor has already returned.
2098 *
2099 * This is also what prevents us from saving the original permissions and
2100 * restoring them later: We can't revoke permissions until all requests
2101 * have completed, and we don't know when that is nor can we really let
2102 * anything else run before we have revoken them to avoid race conditions.
2103 *
2104 * What happens now is that command() in qemu-io-cmds.c can extend the
2105 * permissions if necessary for the qemu-io command. And they simply stay
2106 * extended, possibly resulting in a read-only guest device keeping write
2107 * permissions. Ugly, but it appears to be the lesser evil.
