[issue7336] threading module not properly handling shutdown

[R. Tyler Ballance]

New submission from R. Tyler Ballance <tyler at monkeypox.org>:

Receiving a traceback when shutting down an interpreter with threads 
spawned inside of it:

Traceback (most recent call last):
  File "/usr/lib/python2.6/threading.py", line 497, in __bootstrap
    self.__bootstrap_inner()
  File "/usr/lib/python2.6/threading.py", line 538, in __bootstrap_inner
    (self.name, _format_exc()))
  File "/usr/lib/python2.6/traceback.py", line 235, in format_exc
    etype, value, tb = sys.exc_info()
AttributeError: 'NoneType' object has no attribute 'exc_info'


According to mzz on #Python:

17:29 < mzz> rtyler: I think this is worth a bug report. If you look up 
threading.py:538 you'll find (assuming our line numbers match) that bit 
of code actually goes out of its way to deal with the shutdown problem 
I mentioned, but then it calls into the traceback module, which doesn't.
