// The following is a typical induction puzzle that appears in different dis- //
// guises, and is often also known as the "muddy children puzzle". The variant//
// below is taken from Wikipedia:                                             //
//   In Josephine's Kingdom every woman has to pass a logic exam before being //
// allowed to marry. Every married woman knows about the fidelity of every man//
// in the Kingdom except for her own husband, and etiquette demands that no   //
// woman should tell another about the fidelity of her husband.               //
// A gunshot fired in any house in the Kingdom will be heard in any other     //
// house. Queen Josephine announced that unfaithful men had been discovered   //
// in the Kingdom, and that any woman knowing her husband to be unfaithful was//
// required to shoot him at midnight following the day after she discovered   //
// his infidelity. How did the wives manage this?                             //
//   The interesting fact is here that the problem can only be solved by using//
// time as an additional factor of information, which is only possible if all //
// threads (i.e. wives) are synchronous processes.                            //
