  31. However, Icon *does* have coroutines, which supports lightweight processing
  32. if you add a layer of routines that support preemption, etc.  A very simple
  33. approach is to reimplement (certain) Icon built-in routines to preempt the
  34. coroutine that calls them.  A more sophisticated approach would have to
  35. support a timed preemption mechanism by extending Icon.
