 * In code that queues async I/O operations:
 *
 *   - Obtain a cancellable from the async I/O APIs, and call add_cancellable().
 *
 * To cancel a cancellable:
 *
 *   - Call cancel_cancellable().
 *
 * In async I/O callbacks:
 *
 *   - Check right away if g_cancellable_is_cancelled():  if true, just
