Right, but it should (in KDE) tell you that you have opened files, what 
application is that using them, and, maybe, preloaded konqueror should 
release the directories and not keep them opened even if has all it's windows 
closed.

However, there could be some kind of unsafe button, like "unmount anyway, it 
may cause real problems" or "kill everything accesing it". Sometimes, I get 
angry and 'cdrecord -eject' my CD as well, even if the system is still 
mounted.
