-class catch_threading_exception:
- """Context manager catching threading.Thread exception using
- threading.excepthook.
-
- Storing exc_value using a custom hook can create a reference cycle. The
- reference cycle is broken explicitly when the context manager exits.
-
- Storing thread using a custom hook can resurrect it if it is set to an
- object which is being finalized. Exiting the context manager clears the
- stored object.

- # code spawning a thread which raises an exception
- ...
- # check the thread exception: use cm.args

- # cm.args attribute no longer exists at this point
