Don't forget to shmem.attach.

You can use the (linux) command "ipcs" to take a look at existing shared 
memory segments, and make sure you are indeed attaching to what you think you 
are.  You should also verify that the value of "key" matches up to the real 
key value of the segment (again, using ipcs).
