Hmm, AFAIK that's what it should be out of the box. Certainly on my RHEL6
machine I see
$ ls -ld /dev/shm
drwxrwxrwt. 2 root root 260 Sep 12 10:53 /dev/shm/
Googling suggests that some really old kernels (~2009) might've had issues
with setting this up wrong, but anything in current support ought to
get it right ...
