Umm - I didnt look too close at your implementation, but I dont
think you want to use multiple shm segments. Just allocate one
large (ok, statically sized, but of "we'll never need more mem"
size) segment and do some simple memory management inside it.
(I gave you the pointer to the shm management code I wrote
years ago).
