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::
except Exception:
