## Detailed Description

This information is stored in memory allocated by the Memory_Pool.

This class implements the control block structure that can be used in a "position indepent" fashion, i.e., you don't need to "map" the underlying memory pool to the same address in processes sharing the memory. The tradoff of this flexibility is more expensive malloc/free operations.
