+  //! \param[in] exception_interface An object to send exception messages to.
+  //!
+  //! This method monitors the receive port for exception messages and, if
+  //! not being run by launchd, no-senders notifications. It continues running
+  //! until it has no more clients, indicated by the receipt of a no-senders
+  //! notification, or until Stop() is called. When not being run by launchd, it
+  //! is important to assure that a send right exists in a client (or has been
+  //! queued by `mach_msg()` to be sent to a client) prior to calling this
+  //! method, or it will detect that it is sender-less and return immediately.
+  //!
+  //! All exception messages will be passed to \a exception_interface.
+  //!
+  //! This method must only be called once on an ExceptionHandlerServer object.
+  //!
+  //! If an unexpected condition that prevents this method from functioning is
+  //! encountered, it will log a message and terminate execution. Receipt of an
+  //! invalid message on the receive port will cause a message to be logged, but
+  //! this method will continue running normally.

+  //! is expected that Stop() would be called from a signal handler.
+  //!
+  //! If Stop() is called before Run() it will cause Run() to return as soon as
+  //! it is called. It is harmless to call Stop() after Run() has already
+  //! returned, or to call Stop() after it has already been called.
