so why this does not work?

      8 while not e.isSet():
      9     print "stuff ",

it does *NOT* print (but it should, shouldn't it?), then exits after 3 sec but with error:

Nice try, but you're passing *the result of calling e.set*
as the function parameter to Timer. And the result of calling
e.set () is None. So you're passing None as the function-to-call.
Which it does. And then...

TypeError: 'NoneType' object is not callable

Try passing the function instead:

threading.Timer (3.0, e.set).start ()
