+ * limiting the use cases of the qemu-io HMP command.
+ *
+ * In an ideal world we would unconditionally create a new BlockBackend for
+ * qemuio_command(), but we have commands like 'reopen' and want them to
+ * take effect on the exact BlockBackend whose name the user passed instead
+ * of just on a temporary copy of it.
+ *
+ * Another problem is that deleting the temporary BlockBackend involves
+ * draining all requests on it first, but some qemu-iotests cases want to
+ * issue multiple aio_read/write requests and expect them to complete in
+ * the background while the monitor has already returned.
+ *
+ * This is also what prevents us from saving the original permissions and
+ * restoring them later: We can't revoke permissions until all requests
+ * have completed, and we don't know when that is nor can we really let
+ * anything else run before we have revoken them to avoid race conditions.
+ *
+ * What happens now is that command() in qemu-io-cmds.c can extend the
+ * permissions if necessary for the qemu-io command. And they simply stay
+ * extended, possibly resulting in a read-only guest device keeping write
+ * permissions. Ugly, but it appears to be the lesser evil.
