* @op: a #GMountOperation:
* @message: string containing a mesage to display to the user
* @time_left: the estimated time left before the operation completes, or -1
* @bytes_left: the amount of bytes to be written before the operation
* completes (or -1 if such amount is not known), or zero if the operation
* is completed
*
* Emitted when an unmount operation has been busy for more than some time
* (typically 1.5 seconds).
*
* When unmounting or ejecting a volume, the kernel might need to flush
* pending data in its buffers to the volume stable storage, and this operation
* can take a considerable amount of time. This signal may be emitted several
* times as long as the unmount operation is outstanding, and then one
* last time when the operation is completed, with @bytes_left set to zero.
*
* Implementations of GMountOperation should handle this signal by
* showing an UI notification, and then dismiss it, or show another notification
* of completion, when @bytes_left reaches zero.
*
* If the message contains a line break, the first line should be
* presented as a heading. For example, it may be used as the
* primary text in a #GtkMessageDialog.
