+ * order on all the atomic objects in the system. This graph should
+ * never contain any cycles, as that represents a violation of the
+ * memory model (total ordering). This graph really consists of many
+ * disjoint (unconnected) subgraphs, each graph corresponding to a
+ * separate ordering on a distinct object.
+ *
+ * The edges in this graph represent the "ordered before" relation,
+ * such that <tt>a --> b</tt> means <tt>a</tt> was ordered before
+ * <tt>b</tt>.
