So far the success rate in confusing people who first try to make
long-lived DSA areas and DSM segments is 100%.  Basically, this is all
designed to ensure automatic cleanup of resources in short-lived
scopes.

90% ;)

I got it working with no significant issues for a long lived segment used to store a pool of shm_mq pairs used for a sort of "connection listener" bgworker. Though I only used DSM+ToC, not DSA.
