Test case for precise handler reactivation when nested exceptions are signalled and resumed.

At the moment of writing this, this is broken in Squeak Trunk and the test case would run endlessly if there were no timeout. The reason is that the inner error handler is reactivated when the signal emitted by it is resumed.
