As collections are accessed the * collection is moved toward the front of the list. New * collections are added to the front of the list while old * collections are added to the end of the list. * * The collection model reduces the overhead which would be * incurred if the global heap were a single object, and the * CWFS list allows the library to cheaply choose a collection * for a new object based on object size, amount of free space * in the collection, and temporal locality. *//****************//* Module Setup *//****************//***********//* Headers *//***********//****************//* Local Macros */
