 * Programmer:  Robb Matzke <matzke@llnl.gov>

 *              Friday, March 27, 1998

 *

 * Purpose: Operations on the global heap.  The global heap is the set of

 *      all collections and each collection contains one or more

 *      global heap objects.  An object belongs to exactly one

 *      collection.  A collection is treated as an atomic entity for

 *      the purposes of I/O and caching.

 *

 *      Each file has a small cache of global heap collections called

 *      the CWFS list and recently accessed collections with free

 *      space appear on this list.  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.
