From 4f289e5b9240807d9fa5561fd793981334a9f086 Mon Sep 17 00:00:00 2001 From: Quincey Koziol Date: Mon, 7 Aug 2006 14:51:59 -0500 Subject: [svn-r12551] Description: Refactor fields in heap header to clean out information from dropped features and also group related fields together more nicely. Add fields to heap header for storing information about "huge" objects.
