Which again is the expected behavior in the user's view.

What if user doesn't want?  e.g. DVD/CD media is being burned?

FWIW, I have seen some drives where either the hardware or the drive firmware ignores the eject button while a write operation is in progress (ie, doesn't appear to even send the event, let alone eject the disk).
