Summary: Handling of ISO-images (and maybe other drives, too)
                    broken
           Product: Wine
           Version: 1.1.29
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I just tried to install some software from a set of CD-images (you know, where
you have to switch CDs during install) but discovered that it is impossible to
unmount the first image while the installer is still running:

$ sudo umount /media/tmp/
umount: /media/tmp: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))

"wine eject e:" (e: = /media/tmp) yields the message "Cannot open device for
drive E:", even if the ISO is mounted with "uid=[myusername].
