    a traceback object (see the Reference Manual) which encapsulates the call

-      Assigning the *traceback* return value to a local variable in a function
-      that is handling an exception will cause a circular reference.  Since most
-      functions don't need access to the traceback, the best solution is to use
-      something like ``exctype, value = sys.exc_info()[:2]`` to extract only the
-      exception type and value.  If you do need the traceback, make sure to
-      delete it after use (best done with a :keyword:`try`
-      ... :keyword:`finally` statement) or to call :func:`exc_info` in a
-      function that does not itself handle an exception.
-
-      Such cycles are normally automatically reclaimed when garbage collection
-      is enabled and they become unreachable, but it remains more efficient to
-      avoid creating cycles.
