Asynchronous programming with Tornado

Asynchronous programming can be tricky for beginners, therefore I think it's useful to iron some basic concepts to avoid common pitfalls.

For an explanation about generic asynchronous programming, I recommend you one of the [many][2] [resources][3] [online][4].

I will focus on solely on asynchronous programming in [Tornado][1]. From Tornado's homepage:

	//Kruskal using Union_Find

	#include "stdio.h"
	#include "string.h"
	#include "vector"
	#include "algorithm"
	using namespace std;
	#define pii pair<int, int>
	#define pip pair<int, pii>
	#define F first

	import imaplib, serial, struct, time

	class Mail():
	def __init__(self):
	self.user= 'USER'
	self.password= 'PASS'
	self.ser = serial.Serial('/dev/tty.usbmodem621', 9600)
	self.M = imaplib.IMAP4_SSL('imap.gmail.com', '993')
	self.M.login(self.user, self.password)
