+
+ Cleans up the stack when a :keyword:`with` statement block exits. TOS is the
+ context manager's :meth:`__exit__` bound method. Below that are 1--3 values
+ indicating how/why the finally clause was entered:
+
+ * SECOND = None
+ * (SECOND, THIRD) = (WHY_{RETURN,CONTINUE}), retval
+ * SECOND = WHY_\*; no retval below it
+ * (SECOND, THIRD, FOURTH) = exc_info()

+ In the last case, ``TOS(SECOND, THIRD, FOURTH)`` is called, otherwise
+ ``TOS(None, None, None)``.
+
+ In addition, if the stack represents an exception, *and* the function call
+ returns a 'true' value, this information is "zapped", to prevent ``END_FINALLY``
+ from re-raising the exception. (But non-local gotos should still be resumed.)
