As I understand it, on Linux /dev/shm is a 'filesystem' which represents 
the virtual memory.  There's no such thing on OS X; the VM subsystem is 
handled by a (potentially arbitrarily large number of) pager 
process(es); and the default OS X pager actually uses the root 
filesystem.  If you want chunks of shared memory then you can use the 
shmget(2)/shmat(2) family of functions.  Or you could create a named shm 
object with shm_open(2), delete it with shm_unlink(2).
