The arguments to send_exception are the same as the arguments
173
to ``raise``. If a single exception object is passed in, it
174
will be re-raised when :meth:`wait` is called, generating a
177

178

179
>>> evt.send_exception(RuntimeError())

File "eventlet/event.py", line 120, in wait

187
If it's important to preserve the entire original stack trace,
188
you must pass in the entire :func:`sys.exc_info` tuple.
191
>>> evt = event.Event()
193
... raise RuntimeError()
194
... except RuntimeError:
195
... evt.send_exception(*sys.exc_info())

205
Note that doing so stores a traceback object directly on the
206
Event object, which may cause reference cycles. See the
207
:func:`sys.exc_info` documentation.
