Comment 2 for bug 445289

Correct. This part was changed on the ground that it was breaking a basic design principle of n-osd to manage a queue of notifications and avoid "rushing" the user.

From a protocol point of view, we still honor the call and return a success value. However, the notification is /not/ immediately closed.

However, I think we could remove a notification from the queue, if it is not already on display.
