--- Comment #25 from Bruni earns.61@gmail.com --- AddHandlerShouldWrapExceptions test seems fragile.
Look at Assert.AreEqual (typeof (Exception), e.InnerException.GetType ());
If Mono (extremally unlikely, but nonotheless) raises inner system exception during this test it will be considered passed.
Maybe it's worth using more specific exception class?
