Attempt to allow nested sendNotificationsTo: handling.
Requires Kernel-nice.1391.

The idea is that the handler shall not be active during the handlerAction. But still, we want he inner handlers to be active as was the case with former exception handling.

Please write TestCase documenting expectations and review if this can possibly fit.
