Issue1279

test_dummy_threading fails

Traceback (most recent call last):
  File "dist/Lib/test/test_dummy_threading.py", line 7, in <module>
    import dummy_threading as _threading
  File "/Users/pjenvey/src/java/jython/dist/Lib/dummy_threading.py", 
line 50, in <module>
    import threading
  File "/Users/pjenvey/src/java/jython/dist/Lib/threading.py", line 6, 
in <module>
    from thread import _newFunctionThread
ImportError: cannot import name _newFunctionThread

this is due to the fact that our thread module has _newFunctionThread, 
but dummy_thread does not

Our threading module differs from CPython's so this may be a little more 
involved than it seems

over to jim because technically he broke it with the new threading.py

Someone told us dummy_threading was actually needed for the GAE Python 
SDK. Otherwise we probably wouldn't/shouldn't care at all
