Summary: logging.config.fileConfig doesn't clear logging._handlerList

Initial Comment:
logging.config.fileConfig resets logging._handlers but not logging._handlerList, resulting in tracebacks on shutdown.

e.g.
Error in atexit._run_exitfuncs:
Traceback (most recent call last):
  File "/usr/local/python2.4/lib/python2.4/atexit.py", line 24, in _run_exitfuncs
    func(*targs, **kargs)
  File "/usr/local/python2.4/lib/python2.4/logging/__init__.py", line 1333, in shutdown
    h.close()
  File "/usr/local/python2.4/lib/python2.4/logging/__init__.py", line 674, in close
    del _handlers[self]
KeyError: <zope.testing.testrunner.NullHandler instance at 0x7dddf0>

AFAICT this is fixed in Python 2.5 but has not been backported. Zope cannot use 2.5 as of yet.

Does a backport to 2.4 make sense?
