-
-    In some cases the exception context can be cleared, resulting in None
-    being attempted to be re-raised after an exception handler is run. This
-    can happen when eventlet switches greenthreads or when running an
-    exception handler, code raises and catches an exception. In both
-    cases the exception context will be cleared.
-
-    To work around this, we save the exception state, run handler code, and
-    then re-raise the original exception. If another exception occurs, the
-    saved exception is logged and the new exception is re-raised.
-
-    In some cases the caller may not want to re-raise the exception, and
-    for those circumstances this context provides a reraise flag that
-    can be used to suppress the exception.  For example::

-
-    If another exception occurs and reraise flag is False,
-    the saved exception will not be logged.
-
-    If the caller wants to raise new exception during exception handling
-    he/she sets reraise to False initially with an ability to set it back to
-    True if needed::
-
-      except Exception:
