- The fd's used for book-keeping can change when the clients close and reopen sessions, hence they are not reliable and can lead to incorrect virtual address usage causing corruption or stale data. - Hence use ion cookie for book-keeping which is unique for a given memory fd. - Use LRU method free up/reuse on reaching max limit. - Remove Tonemapper_destroy which is not needed anymore.
