I appreciate the quick responses from the list, and I believe I know the answer ..
yes, I had carefully cd'd out of the /cdrom space and yes, I had carefully stopped all
the processes I knew of referencing the /cd, but after I got lsof recompiled and ran it,
lo! and behold it revealed that indeed (as Caller #3 correctly identified - he wins
the all-expense paid trip to WackyLand!), the the spro_install app had started the license
manager and license daemon running against the cd. Once they were stopped, it dismounted
with no problem!

} My guess is that a license manager process is still hanging around.
} And, distasteful though it may be, you can always reboot.

} We ran into this while setting up our new SparcCluster. It had mounted the CD
} for a diskless boot, and didn't let go. We had to kill the mountd process. We
} found it with fuser, which is a standard part of the OS, so you should be able
} to use it. Not as good as lsof, but maybe good enough to find your culprit.

} i experienced a similar situation on an LX when installing 2.3. my
} guess was that the install process did not exit cleanly. i did a
} reboot and everything was copcetic afterwards.
