DHT Walkthrough Notes

I've put together these notes as I read about DHT's in depth and then learned how the libtorrent implementation based on the Kademlia paper actually works.

What problem does this solve?

400,000,000,000 (400 billion stars), that's a 4 followed by 11 zeros. The number of atoms in the universe is estimated to be around 10^82. A DHT with keys of 160 bits, can have 2^160 possible numbers, which is around 10^48

	// Here is an extremely simple version of work scheduling for multiple
	// processors.
	//
	// The Problem:
	// We have a lot of numbers that need to be math'ed. Doing this on one
	// CPU core is slow. We have 4 CPU cores. We would thus like to use those
	// cores to do math, because it will be a little less slow (ideally
	// 4 times faster actually).
	//
	// The Solution:

	#include <sys/socket.h>
	#include <sys/un.h>
	#include <sys/event.h>
	#include <netdb.h>
	#include <assert.h>
	#include <unistd.h>
	#include <fcntl.h>
	#include <stdio.h>
	#include <errno.h>
