The event-passing protocol was:


- The sender "throws" a message which carries some data
- Any receiver may "catch" the message, which starts its procedures on
the data


I remember at the time, the boss made a 'throw' gesture, which seemed
outrageous. None of the team made a 'catch' gesture, which seemed
hopeless. But the system worked.
