Isn't this complaining about the main shm segment, not a DSM extension?
Also, why is the error "not enough space", rather than something about
a collision? And if this is the explanation, why didn't the previous
runs probing for allowable shmem size fail?
BTW, regardless of the specific properties of random(), surely you ought
to have code in there that would cope with a name collision.
