demo program from upstream

Description of problem:
If logging.config.fileConfig() is called after logging handlers already exist, a KeyError is thrown in the atexit call to logging.shutdown().
    Error in atexit._run_exitfuncs:
    Traceback (most recent call last):
      File "/usr/lib64/python2.4/atexit.py", line 24, in _run_exitfuncs
        func(*targs, **kargs)
      File "/usr/lib64/python2.4/logging/__init__.py", line 1333, in shutdown
        h.close()
      File "/usr/lib64/python2.4/logging/__init__.py", line 674, in close
        del _handlers[self]
    KeyError: <logging.StreamHandler instance at 0x2b5406327878>

Attached is a demo program and a patch from upstream Python bz 1534765 to fix the issue.

it didn't make it for 5.4 as stated, but it's not there either for 5.5. Could it be fixed for 5.6? reported also by a CentOS user. Thanks
