/adata is your working directory now,
as fstat will show you.

I don't believe it; /adata is still your working directory.
I reproduced the above (/media is /adata), and I got this:
# mount /media
# cd /media
# vnconfig svnd0 image.iso
# mount /dev/svnd0 /mnt
# umount /mnt
# umount /media
umount: /media: Device busy
# fstat -f /media
USER CMD PID FD MOUNT INUM MODE R/W SZ|DV
root fstat 16372 wd /media 2 drwxr-x--- r 4608
root ksh 27271 wd /media 2 drwxr-x--- r 4608
# vnconfig -u svnd0
# umount /media
umount: /media: Device busy
# fstat -f /media
USER CMD PID FD MOUNT INUM MODE R/W SZ|DV
root fstat 26416 wd /media 2 drwxr-x--- r 4608
root ksh 27271 wd /media 2 drwxr-x--- r 4608
# cd ..
# fstat -f /media
USER CMD PID FD MOUNT INUM MODE R/W SZ|DV
# umount /media
Before you can umount the mount point, you need to both vnconfig -u
the iso image, and get out of the directory. In particular, I don't
believe the above sequence is real.
