It isn't needed. I personally would prefer an explicit join(), but
according to the documentation, "The entire Python program exits when no
alive non-daemon threads are left.". In other words, the initial thread
is not special and the interpreter will implicitly join() all non-daemon
Which again makes me want to find out in what thread's context the
atexit call is made...
