Unmount notification shows too early

The unmount notification is shown almost immediately and in most cases I can still see the umount process running for ten seconds or more. If I took the notification seriously I would probably lost data. So I need to open a console and watch the umount process, defeating the purpose of the notification. I know I can run udiskie-pmount and just wait for it to end, but I want to unmount volumes from my file manager also.
