Pygame, mouse events and threads

Hi,

  I'm trying to retreive mouse event in a python thread using pygame.
It's not working and I don't know why! Here is the code:

<snippet on>

import pygame, sys, os, threading
from pygame.locals import *
from threading import *

class Display(Thread) :
  """Class managing display"""
  def __init__(self, xRes = 640, yRes = 480):
    Thread.__init__(self)
    #initializing display
    self._xRes = xRes
    self._yRes = yRes
    pygame.display.init()
    self._window = pygame.display.set_mode((xRes, yRes))
    pygame.display.set_caption('Display')
    self._screen = pygame.display.get_surface()
    pygame.display.flip()

    self._log = []
  def input(self, event):
    if event.type == KEYDOWN:
      sys.exit(0)
    else:
      print event
  def run(self):
    print "starting event handling thread"
    i = 0
    while True:
      self.input(pygame.event.wait())

disp = Display()
disp.start()

When I put the content of the run and input functions in the main
thread, it's working, why not in the thread?
