More info:

I did the loop mount as usual:

  sudo mount -o loop my-big.iso /mnt/tmp1

I noticed that each time the loop device number increased. When I do ps, I
found that there are still many loop process in execution:

$ ps -eaf | grep loop
root      5566     1  0 Jan05 ?        00:01:44 [loop0]
root      5597     1  0 Jan05 ?        00:00:00 [loop1]
root      5603     1  0 Jan05 ?        00:00:00 [loop2]
root     10995     1  0 00:28 ?        00:01:41 [loop3]
root     26656     1  0 11:42 ?        00:01:40 [loop4]
root      6234     1  0 17:45 ?        00:00:00 [loop5]

please comment

thanks
