title: python threading.Timer start immediately not at specified time
body: <p>i want to execute a function in every 3 second
  the code works if i call a function without arguments like below:</p>
  
  <pre><code>def mytempfunc():
      print "this is timer!"
      threading.Timer(5, mytempfunc).start()
  </code></pre>
  
  <p>but if i call a function with argument like this:</p>
  
  <pre><code>def myotherfunc(a,b,c,d):
      print "this is timer!"
      threading.Timer(5, myotherfunc(a,b,c,d)).start()
  </code></pre>
  
  <p>the new thread will be created and started immediately without waiting for 5 seconds.
  is there anything that i missed?</p>
