 * substantially improving document load speed in browsing
 * situations. The WebKit cache model controls the behaviors of all of
 * these caches, including various WebCore caches.
 *
 * Browsers can improve document load speed substantially by
 * specifying %WEBKIT_CACHE_MODEL_WEB_BROWSER. Applications without a
 * browsing interface can reduce memory usage substantially by
