DU 4.0D cdfs bug : xcd eject CDROM, even mounted.

xcd (CD_Player for CDE users), used for playing of audio CDs "has a side
effect of making xcd's eject button always work, even when the hardware
eject switch is locked."

I would like to add :
Even when a cdfs filesystem is mounted.
Even when a file reading is in progress (cp, ls, find etc.).
Until the system is up.

The author of the program considerated this as a feature.
(See the source code is available into /usr/example/motif/xcd

By default, you do NOT need to be root for using this command.

Exploit: eject a mounted CD-ROM with xcd, insert another CDROM and ls
-R into CDROM directory. The system will crash.

DEC is informed about this problem.

Workaround: "chmod" or "setld -d". :)
