 Is this the actual use of /dev/shm or can it serve dual purpose and be
 also set up as tmpfs for fifo's? 
Yes this is the actual use of /dev/shm.  In many distros you will find
such a line already in the /etc/fstab.  And yes, it can serve dual
purpose.
  Or...
 |# mkdir /mnt/ramfs|
 [edit /etc/fstab and add the following line]
 |none /mnt/ramfs tmpfs defaults 0 0|
 Then use --with-default-tmpdir=/mnt/ramfs to the JACK configure line
 when you build it. No clients need to be recompiled. 
This is just an older alternative, not better.
