If you don't have anything using the shm, it hardly takes up any space at

   Filesystem           1k-blocks      Used Available Use% Mounted on
   none                    160236         0    160236   0% /dev/shm

In this case, it isn't 160MB that's being used, it's close to 0.

If you *DO* have applications using the shm, removing it is probably the
last thing you want to do.  If you don't have applications using it, you
won't save much RAM by removing it...

 If the code and the comments disagree, then both are probably wrong.
