Summary: logging: findCaller() sometimes raises AttributeError

Initial Comment:
I am invoking the logging.log() function via the C API,
using PyObject_CallFunction(). I have found that
sometimes (not always) the findCaller() function raises
this AttributeError:

AttributeError: 'NoneType' object has no attribute 'f_code'
  File "C:\Program
Files\Python\Lib\logging\__init__.py", line 1052, in
findCaller
    co = f.f_code
  File "C:\Program
Files\Python\Lib\logging\__init__.py", line 1078, in _log
    fn, lno, func = self.findCaller()
  File "C:\Program
Files\Python\Lib\logging\__init__.py", line 1043, in log
    apply(self._log, (level, msg, args), kwargs)
  File "C:\Program
Files\Python\Lib\logging\__init__.py", line 1319, in log
    apply(root

It appears that sometimes, currentframe() is returning
None.

Attached is a patch for logging/__init__.py which
guards against this possibility. Patch is generated
against recent SVN head revision 42958.
