This is the full version of the simple patch:

             break;
         }
         if (!state) {
+            qemu_mutex_unlock(&s->mutex);
             aio_poll(bdrv_get_aio_context(bs), true);
+            qemu_mutex_lock(&s->mutex);
         }
     } while(!state);

that was tested by Richard last week.  Richard, please retest with your test
case.

Thanks,

Paolo

  curl: improve search for unused CURLState
