-
+    real_sleep <seconds>
+
+  The difference between the sleep and real_sleep commands is that sleep
+  uses the delay from the --sleep command-line option if there is one.
+  (If the --sleep option is not given, the sleep command uses the delay
+  specified by its argument.) The real_sleep command always uses the
+  delay specified by its argument.  The logic is that sometimes delays are
+  cpu-dependent, and --sleep can be used to set this delay.  real_sleep is
+  used for cpu-independent delays.
