>Description:
Started playing around with gstat(8) for the first time today, and I noticed 
that geom(4) was reporting a cached, non-present value for a DVD that was 
previously mounted via vlc via cam(4), and was gracefully ejected and removed 
from the system.

It appears that glabel / geom(4) is still tracking the status:

# glabel status
                    Name  Status  Components
iso9660/THE_BIG_LEBOWSKI     N/A  cd0
              label/swap     N/A  ada0s1b

The DVD isn't mounted though:

$ mount | grep cd0
$

However, nothing is actually present as you can see in the following output 
from sysutils/dvd+rw-tools:

$ dvd+rw-mediainfo /dev/cd0 
INQUIRY:                [ATAPI   ][iHAS124   Y     ][BL0V]
GET [CURRENT] CONFIGURATION:
:-( no media mounted, exiting...

Some other important details are included below.

>How-To-Repeat:
1. Get the output from glabel status
2. Play a DVD via vlc.
3. Get the output again from glabel status.
4. Stop DVD and eject.
5. Get the output again from glabel status.

1. will show that the label doesn't exist on a freshly booted system. 3. will 
show that the label exists because the DVD is in use and plugged into geom. 5. 
will show that the label still exists [but shouldn't because it's been 
disconnected from the system and geom(4)].
