I suppose it would be a better solution (and without any waitings):

loop_dev=$(losetup --show -f isofs.iso)
# do mount and other stuff
# do umount
while /bin/true; do
     out=$(losetup -d "$loop_dev" 2>&1)

     if echo "$out" | grep -q -i "No such device"; then
          break
     fi
done

This way we doesn't depend on asynchrony in the loop-driver code.
