There are two issues here:
(1) In the shell, __name__ is not set to __main__, though it probably should be,
(2) the shell stops all threads whenever at the prompt so your thread doesn't
get run because of how the shell works (it's based on our debugger).
We decided not to fix (2) before 3.0 because of the potential for injecting
threading bugs when we add the necessary feature of allowing other threads
to run while one is stopped for "debugging". In many cases, it makes more
sense to stop all threads when one is stopped, but this isn't always the
case and certainly the fact that the shell has inherited this behavior
