 *
 * This file assumes that the monster/object records are initialized
 * to zero, and the race/kind tables have been loaded correctly.  The
 * order of object stacks is currently not saved in the savefiles, but
 * the "next" pointers are saved, so all necessary knowledge is present.
 *
 * We should implement simple "savefile extenders" using some form of
 * "sized" chunks of bytes, with a {size,type,data} format, so everyone
 * can know the size, interested people can know the type, and the actual
 * data is available to the parsing routines that acknowledge the type.
 *
 * Consider changing the "globe of invulnerability" code so that it
 * takes some form of "maximum damage to protect from" in addition to
 * the existing "number of turns to protect for", and where each hit
 * by a monster will reduce the shield by that amount.  XXX XXX XXX
