The present invention relates generally to the field of data processing systems, methods, and computer program products, and, more particularly, to managing a memory pool. Memory pool management may be provided by allocating storage blocks and handles in different parts of a larger memory pool. Two variable size sub-pools may be provided within the memory pool: a storage block sub-pool and a handle sub-pool. Each sub-pool has a variable size and may be allowed to grow until their combined size reaches the size of the memory pool. Both sub-pools may be allowed to grow into the same unused memory space. When a memory request is received from a program, the storage block sub-pool and handle sub-pool may be enlarged to accommodate the request. A storage block and a handle may be allocated to the program from the storage block and handle sub-pools, respectively.
