/*  lo.h: LEAF OBJECT POOL CLASS INTERFACE
 *
 *  $Id: //info.ravenbrook.com/project/mps/custom/cet/version/1.114/code/lo.h#1 $
 *
 *  Copyright (c) 2001 Ravenbrook Limited.  See end of file for license.
 *
 *  The Leaf Object PoolClass is an automatically managed (ie garbage
 *  collected) pool for managing "leaf" objects.  Leaf objects are
 *  objects that have no references or no references that need tracing
 *  (ie the objects they refer too are non-moving and are manually
 *  managed).
 *
 *  This Class has the following features:
 *
 *  Approximately 6% (asymptotically) space overhead on managed objects.
 *
 *  Automatically reclaims memory used by objects no longer reachable
 *  from the roots.
 *
 *  Non-moving.  References to objects in this pool will never change
 *  due to "fixing".
 *
 *  Buffers will always "commit".  When allocating using a buffer,
 *  commit will never fail.
 *
 *  The following caveat applies:
 *
 *  Space and time performance will degrade when fragmentation
 *  increases.
