-/* Notes:
-
-   When scheduling an event, the a delta of zero/one refers to the
-   timeline as follows:
-
-   epoch   0|1              1|2              2|3              3|
-   **queue**|--insn--|*queue*|--insn--|*queue*|--insn--|*queue*|
-     |   ^               ^        |       ^                ^
-     `- +0 ------------ +1 --..   `----- +0 ------------- +1 --..
-
-   When the queue is initialized, the time is set to zero with a
-   number of initialization events scheduled.  Consequently, as also
-   illustrated above, the event queue should be processed before the
-   first instruction.  That instruction being executed during tick 1.
-
-   The simulator main loop may take a form similar to:
-
-       if (halt-/restart-setjmp)
-         {
-
-	   .... // Determine who should go next
-	   last-cpu-nr = get-last-cpu-nr (sd);
-	   next-cpu-nr = get-next-cpu-nr (sd);
-	   events-were-last? = (last-cpu-nr >= nr-cpus);
-	   events-were-next? = (next-cpu-nr >= nr-cpus);
-
-           .... // process any outstanding events
-           sim_events_preprocess (sd, events-were-last?, events-were-next?);
-	   if (events-were-next)
-	     next-cpu-nr = 0;
-
-           .... // prime main loop 
-
-           while (1)
-             {
-	        .... // model one insn of next-cpu-nr .. nr-cpus
-                if (sim_events_tick (sd))
-	          sim_events_process (sd);
-                next-cpu-nr = 0
-	     }
-         }
-
-   NB.  In the above pseudo code it is assumed that any cpu-nr >=
-   nr-cpus is a marker for the event queue. */
